Subject: shmem: fix W=1 build warnings with CONFIG_SHMEM=n
X-Git-Tag: v6.6.17~5460^2~98
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5ff2121a3336a63aa7060cd71534d39dfb1cd2d1;p=platform%2Fkernel%2Flinux-rpi.git

shmem: fix W=1 build warnings with CONFIG_SHMEM=n

With W=1 and CONFIG_SHMEM=n, shmem.c functions have no prototypes so the
compiler emits warnings.
