Subject: [PATCH v2 2/7] staging: bcm2835-audio: don't initialize memory twice
Date:   Wed, 17 Oct 2018 21:01:51 +0200
Message-Id: <20181017190156.30010-3-nsaenzjulienne@suse.de>

Precedence: bulk

The memory is being allocated with devres_alloc(), wich ultimately uses
__GFP_ZERO to call kmalloc. We don't need to zero the memory area again
in bcm2835-audio.
