Offload snd_usb_parse_audio_interface() function which became quite long after adding UAC3 spec support.
Move class-specific parts to separate functions which now produce audioformat structure that is ready to be fed to snd_usb_add_audio_stream().
This also broke Blue Microphones workaround (which relies on audioformat decoded from previous altsetting) into two parts: prepare quirk flag analyzing previous altsetting then use it with current altsetting.

Could you try to split this patch to two parts: one is a simple refactoring to move the code to snd_usb_get_audioformat_uac12(), and another to add snd_usb_get_audioformat_uac3().
In this way, we can see a problem more clearly if it's in the refactoring part.
thanks,
