Описание
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: invalid parameter check in dpu_setup_dspp_pcc
The function performs a check on the "ctx" input parameter, however, it is used before the check.
Initialize the "base" variable after the sanity check to avoid a possible NULL pointer dereference.
