[PATCH V3 1/4] drm/vkms/crc: Implement verify_crc_source callback

This patch implements "verify_crc_source" callback function for Virtual KMS drm driver. Changes Since V1: - update values_cnt in verify_crc_source Changes Since V2: - don't return early from set_crc_source to keep behavior same (Haneen) Cc: Haneen Mohammed Signed-off-by: Mahesh

[PATCH V2 4/4] drm/crc: add pre_crc_read function

This patch implements a callback function which will be called before crc read. In this function driver can implement any preparation work required for successfully reading CRC data. Changes Since V1: - rebase Cc: dri-devel@lists.freedesktop.org Signed-off-by: Mahesh Kumar --- drivers/gpu/drm
