[PATCH] sparc32: fix badzero.cocci warnings

by kernel test robot

From: kernel test robot <lkp(a)intel.com> arch/sparc/mm/srmmu.c:317:42-43: WARNING comparing pointer to 0 arch/sparc/mm/srmmu.c:317:42-43: 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.
