[alsa-devel] [PATCH] ALSA: usb-audio: fix Roland/Cakewalk UM-3G support

[Clemens Ladisch]

Commit 927c9423dd5f2d1c0b93d5e694ab84b4a5559713 (ALSA: usb-audio: add
Edirol UM-3G support) used a wrong quirk type, which would make the
driver refuse to attach with the error message "MIDIStreaming interface
descriptor not found".
