Subject: powerpc/sysfs: Replace sizeof(arr)/sizeof(arr[0]) with ARRAY_SIZE
X-Git-Tag: v5.15~828^2~14
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=590e1e4254458455477e4e857cd00733280a3d73;p=platform%2Fkernel%2Flinux-starfive.git

powerpc/sysfs: Replace sizeof(arr)/sizeof(arr[0]) with ARRAY_SIZE

The ARRAY_SIZE macro is more compact and more formal in linux source.
