Subject: mutex: drop "inline" from mutex_lock() inside kernel/mutex.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b09d2501ed3d294619cbfbcf828ad39324d0e548;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

mutex: drop "inline" from mutex_lock() inside kernel/mutex.c

Impact: build fix

mutex_lock() is was defined inline in kernel/mutex.c, but wasn't
declared so not in <linux/mutex.h>.  This didn't cause a problem until
checkin 3a2d367d9aabac486ac4444c6c7ec7a1dab16267 added the
atomic_dec_and_mutex_lock() inline in between declaration and
definion.

This broke building with CONFIG_ALLOW_WARNINGS=n, e.g. make
allnoconfig.

Either from the source code nor the allnoconfig binary output I cannot
find any internal references to mutex_lock() in kernel/mutex.c, so
presumably this "inline" is now-useless legacy.
