Bug description:
[Impact]
Lenovo ThinkStation P620 is equipped with two USB audio card that don't
fully work.
[Fix]
Give these two cards profile name, so userspace can identify them to add
addition support.
In addition to that, disable non-working element and relax error
handling for speaker, so there's no error left. Otherwise usb-audio
driver will stop working completely.
[Test]
After the patch is applied, `cat /proc/asound/cards` can show correct
profile name for each card. No more error can be spotted from dmesg.
The audio is still not fully working yet, because it requires more work
in userspace ALSA and PulseAudio.
[Regression Potential]
Low. Adding profile name doesn't change any code flow.
The only behavioral change is error handling towards "Speaker."
Becuase it actually relaxes the error handling instead of tightening, so
devices that don't have this issue won't be affected.
