[PATCH] ALSA: hda: Delete an unnecessary check before the function call "kobject_put"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>

The kobject_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.
