Subject: [PATCH] drm/msm/dpu: Fix LM size on a number of platforms
From: Konrad Dybcio <konrad.dybcio@....qualcomm.com>
The register space has grown with what seems to be DPU8.
Bump up the .len to match.
Fixes: e3b1f369db5a ("drm/msm/dpu: Add X1E80100 support")
Fixes: 4a352c2fc15a ("drm/msm/dpu: Introduce SC8280XP")
Fixes: efcd0107727c ("drm/msm/dpu: add support for SM8550")
Fixes: 100d7ef6995d ("drm/msm/dpu: add support for SM8450")
Fixes: 178575173472 ("drm/msm/dpu: add catalog entry for SAR2130P")
