Subject: of: Delete unnecessary check before calling "of_node_put()"
X-Git-Tag: v4.14-rc1~6337^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c46ca3c8310b61d253a39ff1375ea97912794cd1;p=platform%2Fkernel%2Flinux-rpi.git

of: Delete unnecessary check before calling "of_node_put()"

The of_node_put() 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.
