[PATCH 1/2] staging: line6: accept all MIDI channels by default

[Stefan Hajnoczi]

MIDI messages can be filtered by channel so that multiple devices can
coexist on the same MIDI bus.  By default all channels should be
accepted; this is important because Line6 devices seem to have different
default channels.

Accept all MIDI messages by default to avoid confusing users when
messages are silently filtered out.  If filtering is necessary due to
multiple devices on the bus, users can set the midi_mask_transmit and
midi_mask_receive sysfs attributes.
