ALSA: ump: Additional proc output
UMP devices may have more interesting information than the traditional
rawmidi. Extend the rawmidi_global_ops to allow the optional proc
info output and show some more bits in the proc file for UMP.
Note that the "Groups" field shows the first and the last UMP Groups,
and both numbers are 1-based (i.e. the first group is 1).
