In the Linux kernel, the following vulnerability has been resolved:

drm/msm: Fix null pointer dereference on pointer edp

The initialization of pointer dev dereferences pointer edp before edp is null checked, so there is a potential null pointer deference issue. Fix this by only dereferencing edp after edp has been null checked.
