Merge patch series "scsi: pm80xx: Fix expander support"

Niklas Cassel <cassel@kernel.org> says:

Hello all,

Some recent patches broke expander support for the pm80xx driver.

The first two patches in this series make sure that expanders work with
the pm80xx driver again.

It also fixes a bug in pm8001_abort_task() that was found through code
review.

There is also some patches that make the pm80xx driver more robust, so it
is less likely that the expander support will break again in the future.

There is also some minor changes to some other libsas drivers to make use
of the new dev_parent_is_expander() helper.

Please test and review.

Kind regards,
Niklas
