Create a new file intel_hdcp_gsc_message that contain functions which fill the hdcp messages we send to gsc cs this refactor will help us reuse code for Xe later on --v2 -add the missed file for proper build --v3 -use forward declarations instead of #includes [Jani] --v4 -move linux/err.h to intel_hdcp_gsc_message.c from intel_hdcp_gsc_message.h [Jani] --v5 -move linux include on top of drm includes [Uma] Signed-off-by: Suraj Kandpal <suraj.kandpal@intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Uma Shankar <uma.shankar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231009095537.653619-3-suraj.kandpal@intel.com
