The mode_422 variable is initialized to zero, making mode_422 ? 2 : 1
always false.
Since is_dsc_possible is already checked just above, there's no need to
check it again before filling out the DSC settings.
Removing this redundant check simplifies the code without affecting
functionality.

This is fixed in amd-staging-drm-next by the following commit and it's
no longer needed.

This looks to me. Please revise and include this part in V2. Thanks.
