um: net: Eliminate NULL test after alloc_bootmem
Author: Himangi Saraogi <himangi774@gmail.com>
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
