drm: Separate EDID Header Check from EDID Block Check
Provides function drm_edid_header_is_valid() for EDID header check and replaces EDID header check part of function drm_edid_block_valid() by a call of drm_edid_header_is_valid(). This is a prerequisite to extend DDC probing, e. g. in function radeon_ddc_probe() for Radeon devices, by a central EDID header check. Tested for kernel 2.6.35, 2.6.38 and 3.0 Cc: <stable@kernel.org> Signed-off-by: Thomas Reim <reimth@gmail.com> Reviewed-by: Alex Deucher <alexdeucher@gmail.com> Acked-by: Stephen Michaels <Stephen.Micheals@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
