From: kernel test robot <lkp@xxxxxxxxx> drivers/gpu/drm/vmwgfx/vmwgfx_cmd.c:674:25-26: WARNING comparing pointer to 0 Compare pointer-typed values to NULL rather than 0 Semantic patch information: This makes an effort to choose between !x and x == NULL. !x is used if it has previously been used with the function used to initialize x. This relies on type information. More type information can be obtained using the option -all_includes and the option -I to specify an include path.
