The existing GB Audio codec driver is dependent on MSM8994 Audio driver. During the development stage, this dependency was configured due to various changes involved in MSM Audio driver to enable addtional codec card and some of the changes proposed in mainline ASoC framework. However, these are not the real dependencies and some of them can be easily removed. The folowing patch series includes the changes to resolve unnecessary depedencies and make the codec driver functional with the latest kernel. Patch 1,2: Incudes jack framework related changes. Patch 3,4,5: Resolves compilation error observed with the latest kernel and also provides helper APIs required to allow dynamic addition/removal of modules. Patch 6: Finally provides config options and related Makefile changes to enable GB Codec driver. Thanks to Alexandre for raising the headsup [1] and motivating me to provide the necessary changes.
