Subject: ext4: use sizeof(*ptr)
X-Git-Tag: v4.14-rc1~134^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d695a1bea351276615ad270860bc1fbddcfbaeb3;p=platform%2Fkernel%2Flinux-exynos.git

ext4: use sizeof(*ptr)

Replace the specification of data structures by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.
