Subject: pwm: Remove unnecessary check before of_node_put()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8d6cc0738540f97edb021d3b76a4367519f1e5f1;p=linux-beck.git

pwm: Remove unnecessary check before 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.
