In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: move dpuencoder's connector assignment to atomicenable() For cases where the crtc's connectorschanged was set without enable/active getting toggled , there is an atomicenable() call followed by an atomicdisable() but without an atomicmodeset(). This results in a NULL ptr access for the dpuencodergetdrmfmt() call in the atomicenable() as the dpuencoder's connector was cleared in the atomicdisable() but not re-assigned as there was no atomicmodeset() call. Fix the NULL ptr access by moving the assignment for atomicenable() and also use drmatomicgetnewconnectorforencoder() to get the connector from the atomicstate.
