This should really be in drm-fixes, as this bug is now triggering an upstream 
allyesconfig build failure:

 drivers/gpu/drm/gma500/mdfld_dsi_output.c:407:39: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]

as we have this in Makefile:

 # enforce correct pointer usage
 KBUILD_CFLAGS   += $(call cc-option,-Werror=incompatible-pointer-types)

Thanks,
