[PATCH] drm/msm/dsi: remove bpc > 8 entries from allow list

From: Pengyu Luo

Date: Fri Mar 06 2026 - 04:26:06 EST


In upstream the msm, for bpc greater than 8 are not supported yet,
although the hardware block supports this. Remove them until we
support them.

Fixes: b0e71c2637d1 ("drm/msm/dsi: Allow values of 10 and 12 for bits per component")
