Subject: [PATCH 1/2] dma/imx-sdma: call sdma_set_channel_priority after sdma_request_channel
Date: Mon, 9 Jan 2012 16:48:59 +0800 [thread overview]
Message-ID: <1326098940-3697-1-git-send-email-richard.zhao@linaro.org> (raw)
sdma_request_channel sets the default priority. sdma_alloc_chan_resources
should call sdma_set_channel_priority thereafter to over write it.
