[PATCH 1/3] ALSA: korg1212: Adjust eight function calls together with a variable assignment

From: SF Markus Elfring
Date: Thu Nov 16 2017 - 06:53:29 EST

The script "checkpatch.pl" pointed information out like the following.

ERROR: do not use assignment in if condition

Thus fix the affected source code places.
