Subject: [PATCH 34/41] ALSA: usb-audio: Use unsigned char for iface and altsettings fields
Date: Mon, 23 Nov 2020 09:53:40 +0100 [thread overview]
Message-ID: <20201123085347.19667-35-tiwai@suse.de> (raw)
In-Reply-To: <20201123085347.19667-1-tiwai@suse.de>
Just for consistency, use unsigned char for iface and altsetting in
allover places. Also rearrange the field positions of
snd_usb_endpiont and tidy up with some comments.
