--- Comment #4 from Imre Deak <imre.deak at intel.com> ---
The problem is that the test does a fastset and expects that the previous write
to i915_dsc_fec_support takes effect during this fastset. This isn't the case
however, the driver will only look at i915_dsc_fec_support during a full
modeset. So the test should be fixed making sure it does a full modeset. Also
an exit handler should be installed in the test to restore the previous value
of  i915_dsc_fec_support in case things fail midway.

Adding Manasi.
