[RFC PATCH 3/6] drm/msm/dpu1: Wire up DSC mask for active CTL configuration

From: Marijn Suijten
Date: Tue Dec 13 2022 - 18:22:52 EST


Active CTLs have to configure what DSC block(s) have to be enabled, and
what DSC block(s) have to be flushed; this value was initialized to zero
resulting in the necessary register writes to never happen (or would
write zero otherwise). This seems to have gotten lost in the DSC v4->v5
series while refactoring how the combination with merge_3d was handled.

Fixes: 58dca9810749 ("drm/msm/disp/dpu1: Add support for DSC in encoder")
