powerpc/sparse: Fix plain integer as NULL pointer warning
Trivial fix to remove the following sparse warnings: arch/powerpc/kernel/module_32.c:112:74: warning: Using plain integer as NULL pointer arch/powerpc/kernel/module_32.c:117:74: warning: Using plain integer as NULL pointer drivers/macintosh/via-pmu.c:1155:28: warning: Using plain integer as NULL pointer drivers/macintosh/via-pmu.c:1230:20: warning: Using plain integer as NULL pointer drivers/macintosh/via-pmu.c:1385:36: warning: Using plain integer as NULL pointer drivers/macintosh/via-pmu.c:1752:23: warning: Using plain integer as NULL pointer drivers/macintosh/via-pmu.c:2084:19: warning: Using plain integer as NULL pointer drivers/macintosh/via-pmu.c:2110:32: warning: Using plain integer as NULL pointer drivers/macintosh/via-pmu.c:2167:19: warning: Using plain integer as NULL pointer drivers/macintosh/via-pmu.c:2183:19: warning: Using plain integer as NULL pointer drivers/macintosh/via-pmu.c:277:20: warning: Using plain integer as NULL pointer arch/powerpc/platforms/powermac/setup.c:155:67: warning: Using plain integer as NULL pointer arch/powerpc/platforms/powermac/setup.c:247:27: warning: Using plain integer as NULL pointer arch/powerpc/platforms/powermac/setup.c:249:27: warning: Using plain integer as NULL pointer arch/powerpc/platforms/powermac/setup.c:252:37: warning: Using plain integer as NULL pointer arch/powerpc/mm/tlb_hash32.c:127:21: warning: Using plain integer as NULL pointer arch/powerpc/mm/tlb_hash32.c:148:21: warning: Using plain integer as NULL pointer arch/powerpc/mm/tlb_hash32.c:44:21: warning: Using plain integer as NULL pointer arch/powerpc/mm/tlb_hash32.c:57:21: warning: Using plain integer as NULL pointer arch/powerpc/mm/tlb_hash32.c:87:21: warning: Using plain integer as NULL pointer arch/powerpc/kernel/btext.c:160:31: warning: Using plain integer as NULL pointer arch/powerpc/kernel/btext.c:167:22: warning: Using plain integer as NULL pointer arch/powerpc/kernel/btext.c:274:21: warning: Using plain integer as NULL pointer arch/powerpc/kernel/btext.c:285:31: warning: Using plain integer as NULL pointer arch/powerpc/include/asm/hugetlb.h:204:16: warning: Using plain integer as NULL pointer arch/powerpc/mm/ppc_mmu_32.c:170:21: warning: Using plain integer as NULL pointer arch/powerpc/platforms/powermac/pci.c:1227:23: warning: Using plain integer as NULL pointer arch/powerpc/platforms/powermac/pci.c:65:24: warning: Using plain integer as NULL pointer Also use `--fix` command line option from `script/checkpatch --strict` to remove the following: CHECK: Comparison to NULL could be written "!dispDeviceBase" #72: FILE: arch/powerpc/kernel/btext.c:160: + if (dispDeviceBase == NULL) CHECK: Comparison to NULL could be written "!vbase" #80: FILE: arch/powerpc/kernel/btext.c:167: + if (vbase == NULL) CHECK: Comparison to NULL could be written "!base" #89: FILE: arch/powerpc/kernel/btext.c:274: + if (base == NULL) CHECK: Comparison to NULL could be written "!dispDeviceBase" #98: FILE: arch/powerpc/kernel/btext.c:285: + if (dispDeviceBase == NULL) CHECK: Comparison to NULL could be written "strstr" #117: FILE: arch/powerpc/kernel/module_32.c:117: + if (strstr(secstrings + sechdrs[i].sh_name, ".debug") != NULL) CHECK: Comparison to NULL could be written "!Hash" #130: FILE: arch/powerpc/mm/ppc_mmu_32.c:170: + if (Hash == NULL) CHECK: Comparison to NULL could be written "Hash" #143: FILE: arch/powerpc/mm/tlb_hash32.c:44: + if (Hash != NULL) { CHECK: Comparison to NULL could be written "!Hash" #152: FILE: arch/powerpc/mm/tlb_hash32.c:57: + if (Hash == NULL) { CHECK: Comparison to NULL could be written "!Hash" #161: FILE: arch/powerpc/mm/tlb_hash32.c:87: + if (Hash == NULL) { CHECK: Comparison to NULL could be written "!Hash" #170: FILE: arch/powerpc/mm/tlb_hash32.c:127: + if (Hash == NULL) { CHECK: Comparison to NULL could be written "!Hash" #179: FILE: arch/powerpc/mm/tlb_hash32.c:148: + if (Hash == NULL) { ERROR: space required after that ';' (ctx:VxV) #192: FILE: arch/powerpc/platforms/powermac/pci.c:65: + for (;
