Merge branch 'fixes' of git://git.infradead.org/users/vkoul/slave-dma
Pull slave-dmaengine fixes from Vinod Koul: "Another week, time to send another fixes request taking time out of extended weekend for the festivities in this part of the world. We have two fixes from Sergei for rcar driver and one fixing memory leak of edma driver by Geyslan" * 'fixes' of git://git.infradead.org/users/vkoul/slave-dma: dma: edma.c: remove edma_desc leakage rcar-hpbdma: add parameter to set_slave() method rcar-hpbdma: remove shdma_free_irq() calls
