4421d8b5a5 clk: starfive: jh7110-isp: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

ae9977eefc i2c: nomadik: rename private struct pointers from dev to priv
Disambiguate the usage of dev as a variable name; it is usually best to
keep it reserved for struct device pointers. Avoid having multiple
names for the same struct pointer (previously: dev, nmk, nmk_i2c).

Fix whitespace code style; return indented twice, spacing besides infix
operators, align function call arguments to opening parenthesis. Remove
useless cast to unused return value from init_hw(). Introduce local dev
variable in probe() to alias &adev->dev.

0a5a46a6a6 PCI/AER: Generalize TLP Header Log reading
Both AER and DPC RP PIO provide TLP Header Log registers (PCIe r6.1 secs
7.8.4 & 7.9.14) to convey error diagnostics but the struct is named after
AER as the struct aer_header_log_regs. Also, not all places that handle TLP
Header Log use the struct and the struct members are named individually.

Generalize the struct name and members, and use it consistently where TLP
Header Log is being handled so that a pcie_read_tlp_log() helper can be
easily added.

2c12932b8e siox: Don't pass the reference on a master in siox_master_register()
While it's technically fine to pass the ownership of the reference on
a struct siox_master from the caller of siox_master_register() to the
framework this is hard to use. Instead let the framework take its own
reference (that is freed in siox_master_unregister()) and drop the bus
driver's reference in its remove callback.

Merge tag 'drm-fixes-2024-03-08' of https://gitlab.freedesktop.org/drm/kernel

Pull drm fixes from Dave Airlie:
 "Regular fixes (two weeks for i915), scattered across drivers, amdgpu
  and i915 being the main ones, with nouveau having a couple of fixes.
  One patch got applied for udl, but reverted soon after as the
  maintainer has missed some crucial prior discussion.

  Seems quiet and normal enough for this stage.

024a5e6b96 sbus: uctrl: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

trapbase is a pointer to an array of tt_entry, but the code declared it

5d9b7cb383 nexthop: Simplify dump error handling
The only error that can happen during a nexthop dump is insufficient
space in the skb caring the netlink messages (EMSGSIZE). If this happens
and some messages were already filled in, the nexthop code returns the
skb length to signal the netlink core that more objects need to be
dumped.

After commit b5a899154a ("netlink: handle EMSGSIZE errors in the
core") there is no need to handle this error in the nexthop code as it
is now handled in the core.

Simplify the code and simply return the error to the core.

No regressions in nexthop tests:

1cface552a net: add skb_data_unref() helper
Similar to skb_unref(), add skb_data_unref() to save an expensive
atomic operation (and cache line dirtying) when last reference
on shinfo->dataref is released.

I saw this opportunity on hosts with RAW sockets accidentally
bound to UDP protocol, forcing an skb_clone() on all received packets.

These RAW sockets had their receive queue full, so all clone
packets were immediately dropped.

When UDP recvmsg() consumes later the original skb, skb_release_data()
is hitting atomic_sub_return() quite badly, because skb->clone
has been set permanently.

Note that this patch helps TCP TX performance, because
TCP stack also use (fast) clones.

This means that at least one of the two packets (the main skb or
its clone) will no longer have to perform this atomic operation
in skb_release_data().

unittest code that unflattens the unittest overlay base if architecture
is UML because that is always done now.

40f18dbbb4 x86/of: Unconditionally call unflatten_and_copy_device_tree()
Call this function unconditionally so that we can populate an empty DTB
on platforms that don't boot with a firmware provided or builtin DTB.
There's no harm in calling unflatten_device_tree() unconditionally here.
If there isn't a non-NULL 'initial_boot_params' pointer then
unflatten_device_tree() returns early.

7b937cc243 of: Create of_root if no dtb provided by firmware
When enabling CONFIG_OF on a platform where 'of_root' is not populated
by firmware, we end up without a root node. In order to apply overlays
and create subnodes of the root node, we need one. Create this root node
by unflattening an empty builtin dtb.

If firmware provides a flattened device tree (FDT) then the FDT is
unflattened via setup_arch(). Otherwise, the call to
unflatten(_and_copy)?_device_tree() will create an empty root node.

We make of_have_populated_dt() return true only if the DTB was loaded by
firmware so that existing callers don't change behavior after this
patch. The call in the of platform code is removed because it prevents
overlays from creating platform devices when the empty root node is
used.

[sboyd@kernel.org: Update of_have_populated_dt() to treat this empty dtb
as not populated. Drop setup_of() initcall]

dc1460fe1b of: Always unflatten in unflatten_and_copy_device_tree()
We want to populate an empty DT whenever CONFIG_OF is enabled so that
overlays can be applied and the DT unit tests can be run. Make
unflatten_and_copy_device_tree() stop printing a warning if the
'initial_boot_params' pointer is NULL. Instead, simply copy the dtb if
there is one and then unflatten it. If there isn't a DT to copy, then
the call to unflatten_device_tree() is largely a no-op, so nothing
really changes here.

71e721485c drm/xe/pvc: Fix WA 18020744125
With the current state GUC_WA_RCS_REGS_IN_CCS_REGS_LIST could in theory
be removed since there is no render register being added to the list of
compute WAs. However the real issue is that 18020744125 is incomplete
and not setting the RING_HWSTAM on render as it should.

Writing this in RTP is a little more tricky as we want to write to
another's engine base when the match happens: first compute engine and
no render present. So use RING_HWSTAM(RENDER_RING_BASE) instead of the
usual XE_RTP_ACTION_FLAG(ENGINE_BASE).

fcf3f7e2fc raid1: fix use-after-free for original bio in raid1_write_request()
r1_bio->bios[] is used to record new bios that will be issued to
underlying disks, however, in raid1_write_request(), r1_bio->bios[]
will set to the original bio temporarily. Meanwhile, if blocked rdev
is set, free_r1bio() will be called causing that all r1_bio->bios[]
to be freed:

raid1_write_request()
 r1_bio = alloc_r1bio(mddev, bio); -> r1_bio->bios[] is NULL
 for (i = 0;  i < disks; i++) -> for each rdev in conf
  // first rdev is normal
  r1_bio->bios[0] = bio; -> set to original bio
  // second rdev is blocked
  if (test_bit(Blocked, &rdev->flags))
   break

 if (blocked_rdev)
  free_r1bio()
   put_all_bios()
    bio_put(r1_bio->bios[0]) -> original bio is freed

Test scripts:

mdadm -CR /dev/md0 -l1 -n4 /dev/sd[abcd] --assume-clean
fio -filename=/dev/md0 -ioengine=libaio -rw=write -bs=4k -numjobs=1 \
    -iodepth=128 -name=test -direct=1

Since that bios for underlying disks are not allocated yet, fix this
problem by using mempool_free() directly to free the r1_bio.

Instead of creating a hard error and aborting the sandbox creation,
accept file path not usable in the LL_FS_RO and LL_FS_RW environment
variables but only print a warning.  This makes it easier to test, for
instance with LL_FS_RO="${PATH}:/usr/lib:/lib"

Print that we are going to execute the command in the sandbox before
doing so.

Rename "launch" to "execute", and improve header description.

landlock: Use f_cred in security_file_open() hook
Use landlock_cred(file->f_cred)->domain instead of
landlock_get_current_domain() in security_file_open() hook
implementation.

This should not change the current behavior but could avoid potential
race conditions in case of current task's credentials change.

This will also ensure consistency with upcoming audit support relying on
file->f_cred.

Add and use a new get_fs_domain() helper to mask non-filesystem domains.

file->f_cred is set by path_openat()/alloc_empty_file()/init_file() just
before calling security_file_alloc().
