Not all host drivers are PCI drivers - like hisi_sas, which supports a
platform driver - so remove reference to "pcidev".
The debug level is also downgraded to KERN_ERR for the same message.

As a printk without a KERN_<LEVEL> is printed at whatever
CONFIG_MESSAGE_LOGLEVEL_DEFAULT is set to (default: 4 and
rarely unchanged), this is effectively upgraded from a
KERN_WARNING to KERN_ERR.
ah, I thought that it was printed always.
So maybe I'll just leave as-is.
I forgot to mention that checkpatch complains about using printk() -
that's why I changed it.
I believe that always assigning a KERN_<LEVEL>
is good thing so I am not against this change.
Describing the change a bit more correctly than
'debug level downgraded' would be useful.
Right
My preference is a patch like this which
always prefixes "sas: " to each log message
by adding a #define pr_fmt and converts the
bare printks to pr_notice, and converts the
slightly odd sas_printk macro and uses with
a hidden KERN_NOTICE to pr_notice.

Some other subsystem may try to include this header, and gets its

right?
