[PATCH 7/7] drm/msm/dpu: drop VBIF index from the struct dpu_hw_vbif
From: Dmitry Baryshkov
Date: Fri Feb 27 2026 - 13:39:38 EST
Since we don't support and don't use VBIF_NRT, VBIF_RT is the only
possible VBIF type. To simplify the driver, drop vbif_idx from the VBIF
instance structure. As the last users of VBIF_RT and enum dpu_vbif are
gone, drop them too.
