In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: Add missing NULL pointer check for pingpong interface
It is checked almost always in dpu_encoder_phys_wb_setup_ctl(), but in a single place the check is missing. Also use convenient locals instead of phys_enc->* where available.
