commit 0c8d32c27f5cf6e14ca14b4758d1e994eebd50fd upstream.

Forbid port runtime pm by default because it has known hotplug issue.
User can allow it by, for example

echo auto > /sys/devices/pci0000:00/0000:00:1f.2/ata2/power/control

Hi Greg,

Please consider

  0c8d32c27f5c libata: forbid port runtime pm by default, fixing
               regression

for inclusion in the 3.3-stable tree.  (It should apply there cleanly.
The copy in this message is just for easy reference.)

Now applied, thanks for letting me know.
