Public bug reported:
[Impact]
Errors from SMP PHY control commands (e.g. enabling, disabling, resetting phy
links) are currently ignored. This is likely to escalate into problems later in
driver initialization - mostly around reset paths. By logging a message and
returning an error, it should be easier to root cause failures, as well as
avoiding continued use of a phy that has failed to reset.
[Test Case]
Regression testing only on a system that uses a libsas-based driver (hisi_sas)
[Fix]
01929a65dfa13 scsi: libsas: Check SMP PHY control function result
[Regression Risk]
Restricted to systems w/ libsas-based drivers (mvsas, hisi_sas, aic94xx). A
possible risk is that a system was previously functioning normally even though
SMP PHY control commands were failing, and now we'd be logging an error an
aborting the operation.
