Subject: [PATCH 19/41] ALSA: usb-audio: Simplify snd_usb_init_sample_rate() arguments
Date: Mon, 23 Nov 2020 09:53:25 +0100	[thread overview]
Message-ID: <20201123085347.19667-20-tiwai@suse.de> (raw)
In-Reply-To: <20201123085347.19667-1-tiwai@suse.de>

A preliminary change for the later big changes.  This is a minor code
refactoring to drop the unnecessary arguments that can be retrieved in
a different way.
