Merge branch 'fixes' of git://git.infradead.org/users/vkoul/slave-dma 

Pull slave-dmaengine fixes from Vinod Koul:
 "We have three small fixes.

  First one from Andy reverts the devm_request irq as we need to ensure
  the tasklet is killed after irq is freed, so we need to do free irq in
  our code.  Other two from Arnd are fixing the compilation issue in
  omap and sa11x0 drivers with ARM randconfigs"

* 'fixes' of git://git.infradead.org/users/vkoul/slave-dma:
  dmaengine: sa11x0: remove broken #ifdef
  dmaengine: omap: hide filter_fn for built-in drivers
  dmaengine: dw: went back to plain {request,free}_irq() calls
