[PATCH 11/66] ALSA: cmi8330: Fix assignment in if condition

[Takashi Iwai <tiwai@suse.de>]

ISA CMI8330 driver code contains lots of assignments in if condition,
which is a bad coding style that may confuse readers and occasionally
lead to bugs.

This patch is merely for coding-style fixes, no functional changes.
