[Intel-gfx] [PATCH v12 5/6] drm/i915: update the hdcp state with uevent

[Ramalingam C]

drm function to update the content protection property state and to
generate a uevent is invoked from the intel hdcp property work.

Hence whenever kernel changes the property state, userspace will be
updated with a uevent.

v2:
  state update is moved into drm function [daniel]
