Subject: UBIFS: Delete unnecessary checks before the function call "iput"
X-Git-Tag: v4.14-rc1~4342^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=54bcfdf19ec7c2f2788fa76426c91abdc4dab973;p=platform%2Fkernel%2Flinux-rpi.git

UBIFS: Delete unnecessary checks before the function call "iput"

The iput() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
