From 3e1aebef6fb55e35668d2d7cf608cf03f30c904f Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Thu, 4 Mar 2010 19:46:12 +0100 Subject: ALSA: usb-audio: header file cleanups Rename snd-usb-lib to snd-usbmidi-lib as MIDI functions are the only thing it actually contains. Introduce a new header file to only declare these functions. Introduced usbmixer.h for all functions exported by usbmixer.c.
