From a40a3937222c728be925f2d78650cfe9b20be3f5 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 29 Oct 2013 11:59:31 +0100 Subject: ALSA: memalloc: NULL-initialize in snd_malloc_dev_iram() dmab->area and addr fields should be cleared at the head of snd_malloc_dev_iram() as especially dmab->area is used to indicate the allocation failure / fallback.
