Subject: [PATCH 17/66] ALSA: als300: Fix assignment in if condition
Date: Tue,  8 Jun 2021 16:04:51 +0200	[thread overview]
Message-ID: <20210608140540.17885-18-tiwai@suse.de> (raw)
In-Reply-To: <20210608140540.17885-1-tiwai@suse.de>

PCI ALS300 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.
