The __hci_cmd_sync() function doesn't return NULL. Checking for NULL
doesn't make the code safer, it just confuses people.
When a function returns both error pointers and NULL then generally the
NULL is a kind of success case. For example, maybe we look up an item
then errors mean we ran out of memory but NULL means the item is not
found. Or if we request a feature, then error pointers mean that there
was an error but NULL means that the feature has been deliberately
turned off.
In this code it's different. The NULL is handled as if there is a bug
in __hci_cmd_sync() where it accidentally returns NULL instead of a
proper error code. This was done consistently until commit 9e14606d8f
("Bluetooth: msft: Extended monitor tracking by address filter") which
deleted the work around for the potential future bug and treated NULL as
success.
Predicting potential future bugs is complicated, but we should just fix
them instead of working around them. Instead of debating whether NULL
is failure or success, let's just say it's currently impossible and
delete the dead code.

This enables a broadcast sink to be informed if the PA
it has synced with is associated with an encrypted BIG,
by retrieving the socket QoS and checking the encryption
field.
After PA sync has been successfully established and the
first BIGInfo advertising report is received, a new hcon
is added and notified to the ISO layer. The ISO layer
sets the encryption field of the socket and hcon QoS
according to the encryption parameter of the BIGInfo
advertising report event.
After that, the userspace is woken up, and the QoS of the
new PA sync socket can be read, to inspect the encryption
field and follow up accordingly.

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect chinfo.name to be NUL-terminated based on its use with format
strings:
| dev_err(&ctrldev->dev, "failed to create %s channel\n", chinfo.name);
Since chinfo is not default initialized, we should NUL-pad the `name`
field so that the behavior is consistent with what strncpy() provides:
| struct rpmsg_channel_info chinfo;
Considering the above, a suitable replacement is `strscpy_pad` due to
the fact that it guarantees both NUL-termination and NUL-padding on the
destination buffer.

wl->chip.phy_fw_ver_str is obviously intended to be NUL-terminated by
the deliberate comment telling us as much. Furthermore, its only use is
drivers/net/wireless/ti/wlcore/debugfs.c shows us it should be
NUL-terminated since its used in scnprintf:
492 | DRIVER_STATE_PRINT_STR(chip.phy_fw_ver_str);
which is defined as:
| #define DRIVER_STATE_PRINT_STR(x) DRIVER_STATE_PRINT(x, "%s")

We can also see that NUL-padding is not required.
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer

The very fact that a plain-english comment had to be made alongside a
manual NUL-byte assignment for such a simple purpose shows why strncpy
is faulty. It has non-obvious behavior that has to be clarified every
time it is used (and if it isn't then the reader suffers).

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
`extra` is intended to be NUL-terminated which is evident by the manual
assignment of a NUL-byte as well as its immediate usage with strlen().
Moreover, many of these getters and setters are NUL-padding buffers with
memset():
2439 | memset(&tx_power, 0, sizeof(tx_power));
9998 | memset(sys_config, 0, sizeof(struct ipw_sys_config));
10084 | memset(tfd, 0, sizeof(*tfd));
10261 | memset(&dummystats, 0, sizeof(dummystats));
... let's maintain this behavior and NUL-pad our destination buffer.
Considering the above, a suitable replacement is `strscpy_pad` due to
the fact that it guarantees both NUL-termination and NUL-padding on the
destination buffer.
To be clear, there is no bug in the current implementation as
MAX_WX_STRING is much larger than the size of the string literals being
copied from. Also, strncpy() does NUL-pad the destination buffer and
using strscpy_pad() simply matches that behavior. All in all, there
should be no functional change but we are one step closer to eliminating
usage of strncpy().
Do note that we cannot use the more idiomatic strscpy invocation of
(dest, src, sizeof(dest)) as the destination buffer cannot have its size
determined at compile time. So, let's stick with (dest, src, LEN).

The watchdog function is broken on rt2800 series SoCs. This patch
fixes the incorrect watchdog logic to make it work again.
1. Update current wdt queue index if it's not equal to the previous
index. Watchdog compares the current and previous queue index to
judge if the queue hung.
2. Make sure hung_{rx,tx} 'true' status won't be override by the
normal queue. Any queue hangs should trigger a reset action.
3. Clear the watchdog counter of all queues before resetting the
hardware. This change may help to avoid the reset loop.
4. Change hang check function return type to bool as we only need
to return two status, yes or no.

If req->hr_proto->hp_accept() fail, we call fput() twice:
Once in the error path, but also a second time because sock->file
is at that point already associated with the file descriptor. Once
the task exits, as it would probably do after receiving an error
reading from netlink, the fd is closed, calling fput() a second time.
To fix, we move installing the file after the error path for the
hp_accept() call. In the case of errors we simply put the unused fd.
In case of success we can use fd_install() to link the sock->file
to the reserved fd.

Commit a243ecc323 ("net: mdio: xgene: Use device_get_match_data()")
dropped the unconditional use of xgene_mdio_of_match resulting in this
warning:
drivers/net/mdio/mdio-xgene.c:303:34: warning: unused variable 'xgene_mdio_of_match' [-Wunused-const-variable]
The fix is to drop of_match_ptr() which is not necessary because DT is
always used for this driver (well, it could in theory support ACPI only,
but CONFIG_OF is always enabled for arm64).

checkpatch gets confused and treats __attribute__ as a function call.
It complains about white space before "(":
WARNING:SPACING: space prohibited between function name and open parenthesis '('
+ struct netdev_queue_get_rsp obj __attribute__ ((aligned (8)));
No spaces wins in the kernel:
$ git grep 'attribute__((.*aligned(' | wc -l
480
$ git grep 'attribute__ ((.*aligned (' | wc -l
110
$ git grep 'attribute__ ((.*aligned(' | wc -l
94
$ git grep 'attribute__((.*aligned (' | wc -l
63
So, whatever, change the codegen.
Note that checkpatch also thinks we should use __aligned(),
but this is user space code.

Prior to commit 1a074f7618 ("tls: also use init_prot_info in
tls_set_device_offload"), setting TLS_HW on TX didn't touch
prot->aad_size and prot->tail_size. They are set to 0 during context
allocation (tls_prot_info is embedded in tls_context, kzalloc'd by
tls_ctx_create).
When the RX key is configured, tls_set_sw_offload is called (for both
TLS_SW and TLS_HW). If the TX key is configured in TLS_HW mode after
the RX key has been installed, init_prot_info will now overwrite the
correct values of aad_size and tail_size, breaking SW decryption and
causing -EBADMSG errors to be returned to userspace.
Since TLS_HW doesn't use aad_size and tail_size at all (for TLS1.2,
tail_size is always 0, and aad_size is equal to TLS_HEADER_SIZE +
rec_seq_size), we can simply drop this hunk.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
`lc` is already zero-allocated:
| lc = kzalloc(sizeof(*lc), GFP_KERNEL);
... as such, any future NUL-padding is superfluous.
A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on the destination buffer without
unnecessarily NUL-padding.
Let's also go with the more idiomatic `dest, src, sizeof(dest)` pattern
for destination buffers that the compiler can calculate the size for.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect `spec->target_type` to be NUL-terminated based on its use with
a format string after `dm_table_add_target()` is called
| r = dm_table_add_target(table, spec->target_type,
| (sector_t) spec->sector_start,
| (sector_t) spec->length,
| target_params);
... wherein `spec->target_type` is passed as parameter `type` and later
printed with DMERR:
| DMERR("%s: %s: unknown target type", dm_device_name(t->md), type);
It appears that `spec` is not zero-allocated and thus NUL-padding may be
required in this ioctl context.
Considering the above, a suitable replacement is `strscpy_pad` due to
the fact that it guarantees NUL-termination whilst maintaining the
NUL-padding behavior that strncpy provides.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
It seems `cmd->policy_name` is intended to be NUL-terminated based on a
now changed line of code from Commit (c6b4fcbad0 "dm: add cache
target"):
| if (strcmp(cmd->policy_name, policy_name)) { // ...
However, now a length-bounded strncmp is used:
| if (strncmp(cmd->policy_name, policy_name, sizeof(cmd->policy_name)))
... which means NUL-terminated may not strictly be required. However, I
believe the intent of the code is clear and we should maintain
NUL-termination of policy_names.
Moreover, __begin_transaction_flags() zero-allocates `cmd` before
calling read_superblock_fields():
| cmd = kzalloc(sizeof(*cmd), GFP_KERNEL);
Also, `disk_super->policy_name` is zero-initialized
| memset(disk_super->policy_name, 0, sizeof(disk_super->policy_name));
... therefore any NUL-padding is redundant.
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.

Merge series from Uwe Kleine-König <u.kleine-koenig@pengutronix.de>:
This is another series to convert ASoC drivers to use struct
platform_driver:remove_new(). The rockchip one was already send before
but with a wrong subject prefix, the cs42l43 driver is newer than the
last series. The remaining five patches are for driver combos that my
coccinelle patch failed to detect before.
If the cmma no-dat feature is available all pages that are not used for
dynamic address translation are marked as "no-dat" with the ESSA
instruction. This information is visible to the hypervisor, so that the
hypervisor can optimize purging of guest TLB entries. This also means that
pages which are used for dynamic address translation must not be marked as
"no-dat", since the hypervisor may then incorrectly not purge guest TLB
entries.
Region and segment tables allocated via vmem_crst_alloc() are incorrectly
marked as "no-dat", as soon as slab_is_available() returns true.
Such tables are allocated e.g. when kernel page tables are split, memory is
hotplugged, or a DCSS segment is loaded.
Fix this by adding the missing arch_set_page_dat() call.

If the cmma no-dat feature is available the kernel page tables are walked
to identify and mark all pages which are used for address translation (all
region, segment, and page tables). In a subsequent loop all other pages are
marked as "no-dat" pages with the ESSA instruction.
This information is visible to the hypervisor, so that the hypervisor can
optimize purging of guest TLB entries. The initial loop however does not
cover the complete kernel address space. This can result in pages being
marked as not being used for dynamic address translation, even though they
are. In turn guest TLB entries incorrectly may not be purged.
Fix this by adjusting the end address of the kernel address range being
walked.

Get rid of do_fault_error() and move its contents to do_exception(),
which makes do_exception(). With removing do_fault_error() it is also
possible to get rid of the handle_fault_error_nolock() wrapper.
Instead rename do_no_context() to handle_fault_error_nolock().
In result the whole fault handling looks much more like on other
architectures.
