[Intel-gfx] [PATCH 4/4] drm/i915: Add set_protpery function

[shashank.sharma at intel.com]

From: Shashank Sharma <shashank.sharma at intel.com>

Add set_property function in CRTC ops.
This function will be required for color correction properties.
Userspace will do a set_property operation on CRTC object, to
do display tuning or color correction.
