Subject: PowerPC-83xx: Deletion of an unnecessary check before the function call "of_node_put"
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8ac6e995ac17f33a5cc6796c5069488eb9f4abd7;p=linux-beck.git

PowerPC-83xx: Deletion of an unnecessary check before the function call "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.
