From 200ceb962f7b00815259bf3cb2df5a0ac15eb99d Mon Sep 17 00:00:00 2001 From: Barry Song <21cnbao@gmail.com> Date: Sat, 18 May 2013 20:25:00 +0800 Subject: [PATCH] ASoC: dfbmcs320: make the driver common for other BT modules DFBM-CS320 is only one of bluetooth modules using CSR bluetooth chips, we don't want everyone to have a seperate codec driver. anyway, the feature of Bluetooth SCO is same on all platforms, so this patch makes the DFBM-CS320 driver become a common BT SCO link driver.
