Subject: drm/msm/dpu: fix maxlinewidth for writeback block
Git-commit: a370cc392e075de5a4b7f3fb27cdeec0d70b5893
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
Writeback block for sm8250 was using the default maxlinewidth
of 2048. But this is not right as it supports upto 4096.
This should have no effect on most resolutions as we are
still limiting upto maxlinewidth of SSPP for adding the modes.
Fix the maxlinewidth for writeback block on sm8250.
changes in v3:
- correct the Fixes tag
Fixes: 53324b99bd7b ("drm/msm/dpu: add writeback blocks to the sm8250 DPU catalog")
