drm: add drm_edid_to_eld helper extracting SADs from EDID (v2)
Some devices (ATI/AMD cards) don't support passing ELD struct to the hardware but just require filling specific registers and then the hardware/firmware does the rest. In such cases we need to read the info from SAD blocks and put them in the correct registers. agd5f: note that the returned pointer needs to be kfreed as per Christian's suggestion. v2: fix warning Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
