From d82af9f9aab69e82b86450272588c861364f8879 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 16 Nov 2009 12:23:46 +0100 Subject: sound: usb: make the USB MIDI module more independent Remove the dependecy from the USB MIDI code on the snd_usb_audio structure. This allows using the USB MIDI module from another driver without having to pretend to be the generic USB audio driver.
