Colin Ian King 91a340768b drm/msm: Fix null pointer dereference on pointer edp ...

commit 2133c4fc8e1348dcb752f267a143fe2254613b34 upstream.

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.

Addresses-Coverity: ("Dereference before null check")
Fixes: ab5b0107cc ("drm/msm: Initial add eDP support in msm drm driver (v5)")
