drm/i915: HDCP state handling in ddi_update_pipe
The downgrade of the fullmodeset into fastset intel_encoder->update_pipe, in possible scenario, skips the En/Dis-able DDI. Hence breaks the HDCP state change handling. We also don't have any hdcp tests in CI, because the shard runs don't have hdcp capable outputs :-/ So this change fixs it by handling the HDCP state change request at intel_encoder->update_pipe too along with enable and disable of the DDI. Fixes: d19f958db23c ("drm/i915: Enable fastset for non-boot modesets.") v2: Added commit id that broke the HDCP [Daniel] Signed-off-by: Ramalingam C <ramalingam.c@intel.com> cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> cc: Hans de Goede <hdegoede@redhat.com> cc: Daniel Vetter <daniel.vetter@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/1549295080-18353-1-git-send-email-ramalingam.c@intel.com (cherry picked from commit 634852d1f468ccc8cc2e790757c6c1c0f95eb955) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
