Subject: [PATCH 44/66] ALSA: mixart: Fix assignment in if condition
Date: Tue, 8 Jun 2021 16:05:18 +0200 [thread overview]
Message-ID: <20210608140540.17885-45-tiwai@suse.de> (raw)
In-Reply-To: <20210608140540.17885-1-tiwai@suse.de>
PCI miXart driver code contains a few 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.
