Merge branch 'fixes' of git://git.infradead.org/users/vkoul/slave-dma
Pull slave dmaengine fixes from Vinod Koul:
"Four fixes for dw, pl08x, imx-sdma and at_hdmac driver. Nothing
unusual here, simple fixes to these drivers"
* 'fixes' of git://git.infradead.org/users/vkoul/slave-dma:
dmaengine: pl08x: Define capabilities for generic capabilities reporting
dmaengine: dw: append MODULE_ALIAS for platform driver
dmaengine: imx-sdma: switch to dynamic context mode after script loaded
dmaengine: at_hdmac: Fix calculation of the residual bytes
