From: Pratik Vishwakarma <pratik.vishwaka...@amd.com>
DRM_IOCTL_MODE_GETCONNECTOR fails with EINVAL on enabling DRIVER_ATOMIC
With this DRM_IOCTL_MODE_GETCONNECTOR returns all the connector properties.
freesync_property and freesync_capable_property return 0 currently.
TESTS(On Chromium OS on Stoney Only)
* Builds without compilation errors.
* 'atomictest' proceeds after applying patch and fails with vblank event
timed out.
* Chromium OS ui comes up.
