Subject: [PATCH AUTOSEL 5.15 01/10] ALSA: usb-audio: Don't get sample rate for MCT Trigger 5 USB-to-HDMI

From: Forest Crossman <cyrozap@...il.com>

[ Upstream commit d7be213849232a2accb219d537edf056d29186b4 ]

This device doesn't support reading the sample rate, so we need to apply
this quirk to avoid a 15-second delay waiting for three timeouts.
