From 67ada8367c323ce13d0268c87cf09bf8af956e92 Mon Sep 17 00:00:00 2001 From: Thomas Meyer Date: Sat, 6 Aug 2011 13:26:20 +0200 Subject: ALSA: asihpi - use kzalloc() Use kzalloc rather than kmalloc followed by memset with 0 This considers some simple cases that are common and easy to validate Note in particular that there are no ...s in the rule, so all of the matched code has to be contiguous The semantic patch that makes this output is available in scripts/coccinelle/api/alloc/kzalloc-simple.cocci.
