2013-03-11staging/sep: Fix smatch false positive about potential NULL dereference in sep_main.cPeter Huewe1-1/+1
Smatch complains about a potential NULL pointer dereference: sep_main.c:2312 sep_construct_dma_tables_from_lli() error: potential NULL dereference 'info_out_entry_ptr'. info_out_entry_ptr is initialized with NULL and if info_in_entry_ptr is not NULL it gets derefenced. However info_out_entry_ptr is only NULL in the first iteration of the while loop and in this case info_in_entry_ptr is also NULL (as indicated by the comment /* If info entry is null - this is the first table built */ -> this is a false positive. Nevertheless we add a check for info_out_entry_ptr to silence this warning and make it more robust in regard to code changes.

2013-02-11staging: Remove unnecessary OOM messagesJoe Perches2-36/+14
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.

2012-01-30staging: sep: SEP updateMark Allyn12-3215/+8960
This is basically a rewrite so there isn't a nice easy to present way of providing this as a patch series. This patch is a pull of Mark's new driver into the upstream staging area. On top of that are a series of patches by Andy Shevchenko to make it build on the current tree, fix a few things and even get it passed sparse. The new driver supports the kernel crypto layer, passes the coding style checks, passes human taste checks and has proper kernel-doc formatted comments. I've then folded back in some later fixes it was missing that got applied to to the kernel tree. This should be ready for more serious review with a view to migration from the staging tree shortly.
