ALSA: usb-audio: skip the broken mute control on AVerMedia GC553Pro
Skip the nonfunctional master mute control on the AVerMedia Live Gamer
ULTRA S GC553Pro (07ca:1553).
USB tracing shows that GET_CUR returns zero bytes instead of the required
one-byte value, both through usbfs and during ALSA initialization.
SET_CUR succeeds, but switching capture off does not mute HDMI audio.
Before the change, the driver exposed a misleading PCM Capture Switch
and logged: 3:2: failed to get current value for ch 0 (-22)
With the patch applied, the switch and warning are absent. A ten-second
sound recording through PipeWire confirmed that stereo 48 kHz, 16-bit
capture still works.
Tested on NixOS with the patched 7.3.0-rc3 kernel. The USB audio driver
object builds with Clang and W=1; sparse and strict checkpatch pass.
