Pull slave dmaengine fixes from Vinod Koul:
"Here are the fixes in dmaengine subsystem for rc2:
- privatecnt fix for slave dma request API by Christopher
- warn fix for PM ifdef in usb-dmac by Geert
- fix hardware dependency for xgene by Jean"
* 'next' of git://git.infradead.org/users/vkoul/slave-dma:
dmaengine: increment privatecnt when using dma_get_any_slave_channel
dmaengine: xgene: Set hardware dependency
dmaengine: usb-dmac: Protect PM-only functions to kill warning
