drm: NULL pointer dereference [null-pointer-deref] (CWE 476) problem
The Parfait (version 2.1.0) static code analysis tool found the
following NULL pointer derefernce problem.
- drivers/gpu/drm/drm_edid.c
The call to drm_cvt_mode() in function drm_mode_std() for the
HDTV hack resulted in the possibility of accessing a NULL pointer
if drm_mode_std() returned NULL. A check for this added right after
the call to drm_cvt_mode() in this particular area of code.
