From 2bf864ac963c5126a9c7c3dce0958390fb612270 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 6 May 2009 17:30:17 +0200 Subject: ALSA: ice1724 - Allow spec driver to create own routing controls Added a new flag, own_routing, to allow spec drivers to create own routing controls. Also, the basic get/put calls are changed to be external for later use by maya44 driver.
