From 9e38658f703732cb69936553cef4bdb4e5294f3f Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 25 May 2011 09:09:01 +0200 Subject: ALSA: usb-audio: export snd_usb_feature_unit_ctl In order to allow quirks functions to hook up to the standard feature unit op tables, this patch exports a pointer to the struct that is used internally. That way, all the code handling the control can be kept private, and external code can reference the symbol to re-use it.
