== SRU Justification ==
IBM is requesting these three cxlflash patches in the Ubuntu 16.04 HWE and newer
kernels.  All three patches have now landed in mainline v4.15-rc1. 

These commits fix bugs in the existing code - missing VPN could disable a 
card and the write same sector size.

== Fixes ==
285e6670d022 ("scsi: cxlflash: Use derived maximum write same length")
0d4191305e69 ("scsi: cxlflash: Allow cards without WWPN VPD to configure")
d84c198f43c5 ("scsi: cxlflash: Derive pid through accessors")

== Regression Potential ==
Medium.  These patches are not limited to one arch, but they are limited to cxlflash.

== Test Case ==
A test kernel was built with these patches and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
