[PATCH 1/6] ALSA: fireface: rename callback functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It's cleared that Fireface 400 transmits quadlet message for two purposes
at least; received MIDI messages and notification of knob control
operation. Nevertheless current implementation uses callback function name
just for MIDI messages.

This commit renames the callback functions.
