Fixes for v5.19-rc4
- Workaround for parade DSI bridge power sequencing
- Fix for multi-planar YUV format offsets
- Limiting WB modes to max sspp linewidth
- Fixing the supported rotations to add 180 back for IGT
- Fix to handle pm_runtime_get_sync() errors to avoid unclocked access
in the bind() path for dpu driver
- Fix the irq_free() without request issue which was a being hit frequently
in CI.
- Fix to add minimum ICC vote in the msm_mdss pm_resume path to address
bootup splats
- Fix to avoid dereferencing without checking in WB encoder
- Fix to avoid crash during suspend in DP driver by ensuring interrupt
mask bits are updated
- Remove unused code from dpu_encoder_virt_atomic_check()
- Fix to remove redundant init of dsc variable
- Fix to ensure mmap offset is initialized to avoid memory corruption
from unpin/evict
- Fix double runpm disable in probe-defer path
- VMA fenced-unpin fixes
- Fix for WB max-width
- Fix for rare dp resolution change issue
