Subject: [media] cec: Delete an unnecessary check before the function call "rc_free_device"
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d8eddb15e4e436ec44464783687f0057a38fb013;p=linux-beck.git

[media] cec: Delete an unnecessary check before the function call "rc_free_device"

The rc_free_device() 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.
