Subject: [PATCH 62/66] ALSA: serial: Fix assignment in if condition
Date: Tue, 8 Jun 2021 16:05:36 +0200 [thread overview]
Message-ID: <20210608140540.17885-63-tiwai@suse.de> (raw)
In-Reply-To: <20210608140540.17885-1-tiwai@suse.de>
A few ALSA serial drivers contain 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.
