[alsa-devel] [PATCH 1/4] ASoC: firmware: Add support for FW based kcontrols.

Mon Nov 19 19:12:42 CET 2012
This patch adds initial support for firmware based kcontrols by allowing
soc.h to be included by any userspace firmware generation tools and assigns
IDs to the standard ASoC kcontrol types using the kcontrol_new index and IDs
to kcontrol get/put/info functions.
