Subject: Add semaphore.h to kernel_lock.c
X-Git-Tag: firefly_0821_release~21632^2~6
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e48b3deee475134585eed03e7afebe4bf9e0dba9;p=firefly-linux-kernel-4.4.55.git

Add semaphore.h to kernel_lock.c

kernel_lock.c uses DECLARE_MUTEX, up() and down() without explicitly
including asm/semaphore.h.  This is fragile and leaves it vulnerable
to breakage during header reorganisations.
