[ 35/36] imx-drm: imx-drm-core: Export imx_drm_encoder_get_mux_id

[Greg Kroah-Hartman]

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>

commit ea8d15832016b0d07a8121159904e6b1d21b5b8b upstream.

When building imx_v6_v7_defconfig with imx-drm drivers selected as modules, we
get the following build error:

ERROR: "imx_drm_encoder_get_mux_id" [drivers/staging/imx-drm/imx-ldb.ko] undefined!

Export the required function to avoid this problem.
