Pull dmaengine fixes from Vinod Koul:
 "We have few odd driver fixes and one email update change for you this
  time:

   - Driver fixes for k3dma (off by one), pl330 (burst residue
     granularity) and omap-dma (incorrect residue_granularity)

   - Sinan's email update"

* tag 'dmaengine-fix-4.18-rc4' of git://git.infradead.org/users/vkoul/slave-dma:
  dmaengine: k3dma: Off by one in k3_of_dma_simple_xlate()
  dmaengine: pl330: report BURST residue granularity
  MAINTAINERS: Update email-id of Sinan Kaya
