Subject: [PATCH 54/66] ALSA: pcm: Fix assignment in if condition
Date: Tue, 8 Jun 2021 16:05:28 +0200 [thread overview]
Message-ID: <20210608140540.17885-55-tiwai@suse.de> (raw)
In-Reply-To: <20210608140540.17885-1-tiwai@suse.de>
There are a few places doing assignments in if condition in ALSA PCM
core code, 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.
