Subject: dma/imx-sdma: call sdma_set_channel_priority after sdma_request_channel
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3bb5e7caf9641b6a532a55cf3a3621ef814f57ee;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

dma/imx-sdma: call sdma_set_channel_priority after sdma_request_channel

sdma_request_channel sets the default priority. sdma_alloc_chan_resources
should call sdma_set_channel_priority thereafter to over write it.
