Subject: [PATCH 05/66] ALSA: ad1816a: Fix assignment in if condition
Date: Tue, 8 Jun 2021 16:04:39 +0200 [thread overview]
Message-ID: <20210608140540.17885-6-tiwai@suse.de> (raw)
In-Reply-To: <20210608140540.17885-1-tiwai@suse.de>
ISA AD1816A 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.
