[PATCH 0/2] Add support for MEMCPY_SG transfers

Bring back dmaengine API support for scatter-gather memcpy's, which is a
follow-up from a previous patch series in which I wrongly tried to
implement the semantics of a MEMCPY_SG through the Slave SG interface.

The second patch fixes a race condition that I observed when calling
dmaengine_terminate_sync in the Xilinx DMA driver.

  dmaengine: xilinx_dma: Restore support for memcpy SG transfers
  xilinx_dma: Fix read-after-free bug when terminating transfers
