[PATCH 00/38] cxlflash: OpenCXL transport support

[Uma Krishnan]

This patch series adds OpenCXL support to the cxlflash driver. With
this support, new devices using the OpenCXL transport will be supported
by the cxlflash driver along with the existing CXL devices. An effort is
made to keep this transport specific function independent of the existing
core driver that communicates with the AFU.

The first three patches contain a minor fix and staging improvements.

This series is intended for 4.17 and is bisectable.
