Julia Lawall 70a3075d40 FRV: Eliminate NULL test and memset after alloc_bootmem ... As noted by Akinobu Mita in patch b1fceac2b9, alloc_bootmem and related functions never return NULL and always return a zeroed region of memory. Thus a NULL test or memset after calls to these functions is unnecessary. arch/frv/mm/init.c | 2 -- 1 file changed, 2 deletions(-) This was fixed using the following semantic patch.
