[PATCH] drm/msm/a6xx: Fix A702 UBWC mode

From: Konrad Dybcio
Date: Thu Jun 06 2024 - 07:11:31 EST


UBWC_MODE is a one-bit-wide field, so a value of 2 is obviously bogus.

Replace it with the correct value (0).

Fixes: 18397519cb62 ("drm/msm/adreno: Add A702 support")

Closes: https://lore.kernel.org/linux-arm-msm/CACu1E7FTN=kwaDJMNiTmFspALzj2+Q-nvsN5ugi=vz4RdUGvGw@xxxxxxxxxxxxxx/
