MCS-5000/5080 chips belong to the 1st generation of Melfas chips,
manufactured in 2000-2007.

The driver relies on custom platform data (no DT support) and there
never were any users of this driver in the mainline kernel. It is likely
that the driver was (like mcs5000_ts driver) was tested on S3C6410 NCP
board (with Samsung S3C6410 SoC), but the touchkey device was never
added to the board file. This board was removed in v6.3 in commit
743c8fbb ("ARM: s3c: remove most s3c64xx board support").

Remove the driver since there are no users.

  fortify: fix warnings in fortify tests with KASAN
  kbuild: rpm-pkg: avoid the warnings with dtb's listed twice
  kbuild: Make ld-version.sh more robust against version string changes

When a software KASAN mode is enabled, the fortify tests emit warnings
on some architectures.

For example, for ARCH=arm, the combination of CONFIG_FORTIFY_SOURCE=y
and CONFIG_KASAN=y produces the following warnings:

    TEST    lib/test_fortify/read_overflow-memchr.log
  warning: unsafe memchr() usage lacked '__read_overflow' warning in lib/test_fortify/read_overflow-memchr.c
    TEST    lib/test_fortify/read_overflow-memchr_inv.log
  warning: unsafe memchr_inv() usage lacked '__read_overflow' symbol in lib/test_fortify/read_overflow-memchr_inv.c
    TEST    lib/test_fortify/read_overflow-memcmp.log
  warning: unsafe memcmp() usage lacked '__read_overflow' warning in lib/test_fortify/read_overflow-memcmp.c

  warning: unsafe memcmp() usage lacked '__read_overflow2' warning in lib/test_fortify/read_overflow2-memcmp.c
     [ more and more similar warnings... ]

Commit 9c2d1328 ("kbuild: provide reasonable defaults for tool
coverage") removed KASAN flags from non-kernel objects by default.
It was an intended behavior because lib/test_fortify/*.c are unit
tests that are not linked to the kernel.

As it turns out, some architectures require -fsanitize=kernel-(hw)address
to define __SANITIZE_ADDRESS__ for the fortify tests.

Without __SANITIZE_ADDRESS__ defined, arch/arm/include/asm/string.h
defines __NO_FORTIFY, thus excluding <linux/fortify-string.h>.

This issue does not occur on x86 thanks to commit 4ec4190b
("kasan, x86: don't rename memintrinsics in uninstrumented files"),
but there are still some architectures that define __NO_FORTIFY
in such a situation.

Set KASAN_SANITIZE=y explicitly to the fortify tests.

After [1] in upstream LLVM, ld.lld's version output became slightly
different when the cmake configuration option LLVM_APPEND_VC_REV is
disabled.

Before:

  Debian LLD 19.0.0 (compatible with GNU linkers)

After:

  Debian LLD 19.0.0, compatible with GNU linkers

This results in ld-version.sh failing with

  scripts/ld-version.sh: 18: arithmetic expression: expecting EOF: "10000 * 19 + 100 * 0 + 0,"

because the trailing comma is included in the patch level part of the
expression. While [1] has been partially reverted in [2] to avoid this
breakage (as it impacts the configuration stage and it is present in all
LTS branches), it would be good to make ld-version.sh more robust
against such miniscule changes like this one.

Use POSIX shell parameter expansion [3] to remove the largest suffix
after just numbers and periods, replacing of the current removal of
everything after a hyphen. ld-version.sh continues to work for a number
of distributions (Arch Linux, Debian, and Fedora) and the kernel.org
toolchains and no longer errors on a version of ld.lld with [1].

The locking rules in the driver came from era when sysfs attributes
could live past the point of time when device would be unbound from
the driver, and so used module-global semaphore (potentially shared
between multiple yealink devices). Thankfully these times are long
gone and attributes will not be accessible once they are removed.

Simplify the logic by moving to per-device mutex, stop checking if
there is driver data instance attached to the interface, and use
guard notation to acquire the mutex.

Instead of manually creating driver-specific device attributes
set struct usb_driver->dev_groups pointer to have the driver core
do it.

This also fixes issue with the attribute not being deleted on driver
unbind.

Pull btrfs fixes from David Sterba:
 "Fix a regression in extent map shrinker behaviour.

  In the past weeks we got reports from users that there are huge
  latency spikes or freezes. This was bisected to newly added shrinker
  of extent maps (it was added to fix a build up of the structures in
  memory).

  I'm assuming that the freezes would happen to many users after release
  so I'd like to get it merged now so it's in 6.10. Although the diff
  size is not small the changes are relatively straightforward, the
  reporters verified the fixes and we did testing on our side.

  The fixes:

   - adjust behaviour under memory pressure and check lock or scheduling
     conditions, bail out if needed

   - synchronize tracking of the scanning progress so inode ranges are
     not skipped or work duplicated

   - do a delayed iput when scanning a root so evicting an inode does
     not slow things down in case of lots of dirty data, also fix
     lockdep warning, a deadlock could happen when writing the dirty
     data would need to start a transaction"
