From: Lad, Prabhakar <prabhakar.cse...@gmail.com>
export the symbols which are used by two modules vpif_capture and
vpif_display. renamed "ch_params" to "vpif_ch_params" so as to avoid
name collision.
This patch fixes following error:
ERROR: "ch_params" [drivers/media/platform/davinci/vpif_display.ko] undefined!
ERROR: "vpif_ch_params_count" [drivers/media/platform/davinci/vpif_display.ko]
undefined!
ERROR: "vpif_base" [drivers/media/platform/davinci/vpif_display.ko] undefined!
ERROR: "ch_params" [drivers/media/platform/davinci/vpif_capture.ko] undefined!
ERROR: "vpif_ch_params_count" [drivers/media/platform/davinci/vpif_capture.ko]
undefined!
ERROR: "vpif_base" [drivers/media/platform/davinci/vpif_capture.ko] undefined!

Changes for v3:
1: prefixed "ch_params" with driver name to make it "vpif_ch_params"
as pointed by Mauro.
Changes for v2:
1: use EXPORT_SYMBOL_GPL instead of EXPORT_SYMBOL() as pointed by
Sekhar.
