Subject: kernel/auditsc.c: use kzalloc instead of kmalloc+memset
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3f68613f39cdc242fa2e872ac04a802e7cc7b7cb;p=openwrt%2Fstaging%2Fblogic.git

kernel/auditsc.c: use kzalloc instead of kmalloc+memset

In audit_alloc_context() use kzalloc instead of kmalloc+memset.  Also
rename audit_zero_context() to audit_set_context(), to represent it's
inner workings properly.

[akpm@linux-foundation.org: remove audit_set_context() altogether - fold it into its caller]
