Subject: [PATCH 07/66] ALSA: cs423x:  Fix assignment in if condition
Date: Tue,  8 Jun 2021 16:04:41 +0200	[thread overview]
Message-ID: <20210608140540.17885-8-tiwai@suse.de> (raw)
In-Reply-To: <20210608140540.17885-1-tiwai@suse.de>

ISA CS423x 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.
