[PATCH 7/8] wireless: Remove unnecessary alloc/OOM messages, alloc cleanups
Joe Perches
joe at perches.com
Sun Feb 3 22:28:14 EST 2013
alloc failures already get standardized OOM
messages and a dump_stack.
Convert kzalloc's with multiplies to kcalloc.
Convert kmalloc's with multiplies to kmalloc_array.
Remove now unused variables.
Remove unnecessary memset after kzalloc->kcalloc.
Whitespace cleanups for these changes.
