Subject: Add semaphore.h to kernel_lock.c
X-Git-Tag: v2.6.26-rc1~1155^2~6
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=e48b3deee475134585eed03e7afebe4bf9e0dba9;p=linux-2.6-omap-h63xx.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.
