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: "vpif_base" [drivers/media/platform/davinci/vpif_capture.ko] undefined! make[1]: *** [__modpost] Error 1 Reported-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Lad, Prabhakar <prabhakar.csengg@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
