* ALSA: usb-audio: support partially write-protected UAC2 controlsDaniel Mack2010-05-311-0/+2
| | | | | | | | | | | | | So far, UAC2 controls are marked read-only if any of the channels are marked read-only in the descriptors. Change this behaviour and - mark them writeable unless all channels are read-only - store the read-only mask in usb_mixer_elem_info and - check the mask again in set_cur_mix_value(), and bail out for write-protected channels.
