This patch series adds OCXL support to the cxlflash driver. With this
support, new devices using the OCXL 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.
v3 Changes:
- Addressed comments by Frederic Barrat
- Resolved IDR initialization bug
- Properly identify functions that do not have an AFU defined
- Added 3 new patches to the end of the series which resolve corner cases
v2 Changes:
- Replaced OpenCXL with OCXL in the commit messages and comments
