It seems that we have finished addressing all the remaining
issues regarding -Wstringop-overflow. So, we are now in good
shape to enable this compiler option globally.

Pull coccinelle updates from Julia Lawall:
 "Updates to the device_attr_show semantic patch to reflect the new
  guidelines of the Linux kernel documentation.

  The problem was identified by Li Zhijian <lizhijian@fujitsu.com>, who
  proposed an initial fix"

* tag 'coccinelle-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/jlawall/linux:
  coccinelle: device_attr_show: simplify patch case
  coccinelle: device_attr_show: Adapt to the latest Documentation/filesystems/sysfs.rst

Replacing the final expression argument by ... allows the format
string to have multiple arguments.

It also has the advantage of allowing the change to be recognized as
a change in a single statement, thus avoiding adding unneeded braces.

The existing mainline clang development version encounters difficulties
compiling the LoongArch kernel module. It is anticipated that this issue
will be resolved in the upcoming 18.0.0 release. To prevent user
confusion arising from broken builds, it is advisable to raise the
minimum required clang version for LoongArch to 18.0.0.
