> This series has been tested locally.
> With the introduction of i915_dsc_bpp debugfs the expectation is that
> whenever there is force_dsc_en set, force_dsc_bpp should have a valid
> value for that format which is between bpp to bpp-1.
> 
> This makes the older test kms_dp_dsc --basic fail as in that case
> force_dsc_bpp would be 0 and is not a valid value.
> 
> Have tested with local changes on the same.
> The series https://patchwork.freedesktop.org/series/91772/
> have the base patches and would need some work on the debugfs name
> change, giving default value for force_dsc_bpp in case of basic-dsc-enable
> test cases, clearing up of the force_dsc_bpp value while exiting the test.
> Which will be floated shortly.
> 
> Have added minor fix on the feci debugfs interface.
> If further changes are needed on the same will float them in a different
> series.
