drm/i915/dp: Fail state computation for invalid DSC source input BPP values

Browse source

[ Upstream commit 338465490c ]

There is no reason to accept an invalid minimum/maximum DSC source input
BPP value (i.e a minimum DSC input BPP value above the maximum pipe BPP
or a maximum DSC input BPP value below the minimum pipe BPP value), fail
the state computation in these cases.
