Date: Wed, 6 Nov 2013 10:16:20 +0000 From: Lee Jones <lee.jones@...aro.org> To: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Cc: linus.walleij@...aro.org, Lee Jones <lee.jones@...aro.org>, alsa-devel@...a-project.org, Mark Brown <broonie@...nel.org> Subject: [PATCH 08/13] ASoC: generic-dmaengine-pcm: Clear slave_config memory We currently assume that the DMA Slave Config will be fully populated by the platform, however some DMA Engines make decisions based on zero (default) flags such as DMA_SLAVE_BUSWIDTH_UNDEFINED and as this is a static declaration we need to memset it to clear the data area.
