  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
