From: Joe Perches Date: Thu, 7 Feb 2013 11:46:27 +0000 (+0000) Subject: drivers: net: Remove remaining alloc/OOM messages X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=14f8dc49532f765968ff37c3b99edbeb99004ace;p=linux-beck.git drivers: net: Remove remaining alloc/OOM messages alloc failures already get standardized OOM messages and a dump_stack. For the affected mallocs around these OOM messages: Converted kmallocs with multiplies to kmalloc_array. Converted a kmalloc/memcpy to kmemdup. Removed now unused stack variables. Removed unnecessary parentheses. Neatened alignment. Signed-off-by: Joe Perches Acked-by: Arend van Spriel Acked-by: Marc Kleine-Budde Acked-by: John W. Linville Signed-off-by: David S.
