From: Joe Perches Date: Mon, 11 Feb 2013 17:41:29 +0000 (-0800) Subject: staging: Remove unnecessary OOM messages X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=78110bb8dc4a7ff331bfa3cfe7d4e287cfb3f22b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git staging: Remove unnecessary OOM messages alloc failures already get standardized OOM messages and a dump_stack. For the affected mallocs around these OOM messages: Converted kzallocs with multiplies to kcalloc. Converted kmallocs with multiplies to kmalloc_array. Converted a kmalloc/strlen/strncpy to kstrdup. Moved a spin_lock below a removed OOM message and removed a now unnecessary spin_unlock. Neatened alignment and whitespace.
