drm/crc: Cleanup crtc_crc_open function
This patch make changes to allocate crc-entries buffer before enabling CRC generation. It moves all the failure check early in the function before setting the source or memory allocation. Now set_crc_source takes only two variable inputs, values_cnt we already gets as part of verify_crc_source. Changes since V1: - refactor code to use single spin lock Changes since V2: - rebase Changes since V3: - rebase on top of VKMS driver Signed-off-by: Mahesh Kumar <mahesh1.kumar@intel.com> Cc: dri-devel@lists.freedesktop.org Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Haneen Mohammed <hamohammed.sa@gmail.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Acked-by: Leo Li <sunpeng.li@amd.com> (V2) Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> (V3) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180821083858.26275-3-mahesh1.kumar@intel.com
