The commits in question do not proove that ACPI IDs exist.
Quite likely it was a cargo cult addition while doing that
for DT-based enumeration. Drop most likely fake ACPI IDs.
The to be removed IDs has been checked against the following resources:
1) DuckDuckGo
2) Google
3) MS catalog: https://www.catalog.update.microsoft.com/Search.aspx
This gives no useful results in regard to DSDT, moreover, the official
vendor ID in the registry for Lite-On is LCI.

The complexity of config guards needed for ACPI_PTR() is not worthwhile
for the small amount of saved data. This example was doing it correctly
but I am proposing dropping this so as to reduce chance of cut and paste
where it is done wrong. Also drop now unneeded linux/acpi.h include and
added linux/mod_devicetable.h for struct acpi_device_id definition.

A shift-out-of-bounds issue was identified by UBSAN in the
tegra_qspi_fill_tx_fifo_from_client_txbuf() function.
UBSAN: shift-out-of-bounds in drivers/spi/spi-tegra210-quad.c:345:27
shift exponent 32 is too large for 32-bit type 'u32' (aka 'unsigned int')
Call trace:
tegra_qspi_start_cpu_based_transfer
The problem arises when shifting the contents of tx_buf left by 8 times
the value of i, which can exceed 4 and result in an exponent larger than
32 bits.
Resolve this by restrict the value of i to be less than 4, preventing
the shift operation from overflowing.

qcom/qdsp6 want to use irregular rtd->id because of its topology.
Current code is calculating it at soc_init_pcm_runtime() which calls
soc_new_pcm(), and it doesn't save it to rtd->id.
Let's calculate and save it to rtd at snd_soc_add_pcm_runtime()
which create rtd and connect related components.
But, this feature should be implemented by using "dai_link" instead
of "component". Add FIXME as comment.

Current rtd has "num". It sounds/looks like size of rtd or something,
but it will be mainly used at snd_pcm_new() as "device index".
This naming is confusable. Let's rename it to "id"

Currently, RK809's BUCK3 regulator is modelled in the driver as a
configurable regulator with 0.5-2.4V voltage range. But the voltage
setting is not actually applied, because when bit 6 of
PMIC_POWER_CONFIG register is set to 0 (default), BUCK3 output voltage
is determined by the external feedback resistor. Fix this, by setting
bit 6 when voltage selection is set. Existing users which do not
specify voltage constraints in their device trees will not be affected
by this change, since no voltage setting is applied in those cases,
and bit 6 is not enabled.

generic_permission() turned out to be costlier than expected. The reason
is that acl_permission_check() performs owner checks that involve costly
pointer dereferences.
There's already code that skips expensive group checks if the group and
other permission bits are the same wrt to the mask that is checked. This
logic can be extended to also shortcut permission checking in
acl_permission_check().
If the inode doesn't have POSIX ACLs than ownership doesn't matter. If
there are no missing UGO permissions the permission check can be
shortcut.

Commit ee7f366699 ("tracefs: Have new files inherit the ownership of
their parent") and commit 48b27b6b51 ("tracefs: Set all files to the
same group ownership as the mount option") introduced a new gid mount
option that allows specifying a group to apply to all entries in tracefs.
Document this in the tracing readme.

Commit 78ff640819 ("vfs: Convert tracefs to use the new mount API")
converted tracefs to use the new mount APIs caused mount options
(e.g. gid=<gid>) to not take effect.
The tracefs superblock can be updated from multiple paths:
- on fs_initcall() to init_trace_printk_function_export()
- from a work queue to initialize eventfs
tracer_init_tracefs_work_func()
- fsconfig() syscall to mount or remount of tracefs
The tracefs superblock root inode gets created early on in
init_trace_printk_function_export().
With the new mount API, tracefs effectively uses get_tree_single() instead
of the old API mount_single().
Previously, mount_single() ensured that the options are always applied to
the superblock root inode:
(1) If the root inode didn't exist, call fill_super() to create it
and apply the options.
(2) If the root inode exists, call reconfigure_single() which
effectively calls tracefs_apply_options() to parse and apply
options to the subperblock's fs_info and inode and remount
eventfs (if necessary)
On the other hand, get_tree_single() effectively calls vfs_get_super()
which:
(3) If the root inode doesn't exists, calls fill_super() to create it
and apply the options.
(4) If the root inode already exists, updates the fs_context root
with the superblock's root inode.
(4) above is always the case for tracefs mounts, since the super block's
root inode will already be created by init_trace_printk_function_export().
This means that the mount options get ignored:
- Since it isn't applied to the superblock's root inode, it doesn't
get inherited by the children.
- Since eventfs is initialized from a separate work queue and
before call to mount with the options, and it doesn't get remounted
for mount.
Ensure that the mount options are applied to the super block and eventfs
is remounted to respect the mount options.
To understand this better, if fstab has the following:
tracefs /sys/kernel/tracing tracefs nosuid,nodev,noexec,gid=tracing 0 0
On boot up, permissions look like:
# ls -l /sys/kernel/tracing/trace
-rw-r----- 1 root root 0 Nov 1 08:37 /sys/kernel/tracing/trace
When it should look like:
# ls -l /sys/kernel/tracing/trace
-rw-r----- 1 root tracing 0 Nov 1 08:37 /sys/kernel/tracing/trace
