[PATCH v1 0/6] dmaengine: miscellaneous fixes for ioat, switchtec_dma and plx_dma

[Logan Gunthorpe]

When reviewing the recent switchtec patchset, the Sashiko bot noticed
a handful of pre-existing problems in the ioat and switchtec drivers.
Additionally, I've included:

 * A fix for a plx-dma issue that was reported on the list[1] a few
   weeks ago.
 * A potential issue I noticed while reviewing the code where pointers
   need to be set to NULL.

These fixes are all valid and independent of the work I was doing so
I've sent them as their own submission. I'm still working on the rest
of the feedback Sashiko gave me on that submission.

Thanks,

Logan
