Merge branch 'fixes' of git://git.infradead.org/users/vkoul/slave-dma
Pull slave-dma fixes from Vinod Koul: "This request brings you two small fixes. First one for fixing dereference of freed descriptor and second for fixing sdma bindings for it to work for imx25. I was planning to send this about 10days ago but then I had to proceed on my paternity leave and didnt get chance to send this. Now got a bit of time from dady duties :)" * 'fixes' of git://git.infradead.org/users/vkoul/slave-dma: dma: sdma: Add imx25 compatible dma: ste_dma40: don't dereference free:d descriptor
