From f09d4f26f6192ec9b060047cc7126e01980bb36c Mon Sep 17 00:00:00 2001 From: Jeeja KP Date: Fri, 21 Aug 2015 21:36:21 +0530 Subject: [PATCH] ALSA: hdac: Remove the usage of key for host stream hdac_ext_stream assign doesn't require key mapping as in case of hdac_stream. So for host stream, the key to device mapping needs to be removed.
