ALSA: es1688_lib: Deletion of an unnecessary check before the function call "release_and_free_resource"
The release_and_free_resource() 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. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
