um: net: Eliminate NULL test after alloc_bootmem
alloc_bootmem and related functions never return NULL. Thus a NULL test or memset after calls to these functions is unnecessary. The following Coccinelle semantic patch was used for making the change: @@ expression E; statement S; @@ E = \(alloc_bootmem\|alloc_bootmem_low\|alloc_bootmem_pages\|alloc_bootmem_low_pages\)(...) ... when != E - if (E == NULL) S Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Richard Weinberger <richard@nod.at>
