[PATCH 0/6] plx_dma fixes

[Logan Gunthorpe <logang@deltatee.com>]

I got out my old PLX hardware to cleanup the issues that Sashiko reported
after I submitted another fix earlier this year. While testing, I also hit
a sleeping BUG that trigger when unbinding the driver which is fixed
in the first patch.

I think every patch is easily understood and independent.

This series is based off of v7.4rc1.

Thanks,

Logan
