This is v3 of the patchset to merge what Tobias Hoffman and Robin Gareus have done to enable the Focusrite Scarlett mixers for use with ALSA.
I have split the commits into hopefully a logical series. First the original quirk is reverted for one model of a Scarlett device. Next an additional structure is added to be able to more easily reuse usb_mixer_elem_info. After this mixer functions that were useful to this code were made public. Finally the last patch adds the necessary functions to make this mixer work.
I have only tested this on my own device which is a Focusrite Scarlett 18i8, any additional testing would be appreciated.
