md: raid1: kill warning on powerpc_pseries
This patch kills the warning reported on powerpc_pseries, and actually we don't need the initialization. After merging the md tree, today's linux-next build (powerpc pseries_le_defconfig) produced this warning: drivers/md/raid1.c: In function 'raid1d': drivers/md/raid1.c:2172:9: warning: 'page_len$' may be used uninitialized in this function [-Wmaybe-uninitialized] if (memcmp(page_address(ppages[j]), ^ drivers/md/raid1.c:2160:7: note: 'page_len$' was declared here int page_len[RESYNC_PAGES]; ^ Signed-off-by: Ming Lei <tom.leiming@gmail.com> Signed-off-by: Shaohua Li <shli@fb.com>
