Subject: dmaengine: imx-sdma: correct sdmac->status in sdma_handle_channel_loop()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1e9cebb42de57f1243261939c77ab5b0f9bcf311;p=deliverable%2Flinux.git

dmaengine: imx-sdma: correct sdmac->status in sdma_handle_channel_loop()

sdma_handle_channel_loop() is the handler of cyclic tx.  One period
success does not really mean the success of the tx.  Instead of
DMA_SUCCESS, DMA_IN_PROGRESS should be the one to tell.
