[ 050/150] ALSA: usb-audio: fix Roland A-PRO support

[Greg Kroah-Hartman]

3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Clemens Ladisch <clemens@xxxxxxxxxx>

commit 7da58046482fceb17c4a0d4afefd9507ec56de7f upstream.

The quirk for the Roland/Cakewalk A-PRO keyboards accidentally used the
wrong interface number, which prevented the driver from attaching to the
device.
