This is almost certainly wrong (same for the other drivers you converted) 
as they now no longer support hibernation, which requires different ops.
Please see: http://lkml.org/lkml/2009/7/25/118.

You also seem to have handled the #ifndef CONFIG_PM case incorrectly.
See http://lkml.org/lkml/2009/8/3/253 for an example how it can be done.

There have already been several threads on lkml discussing this. Please 
search for posts with dev_pm_ops in the subject if you want more 
information.

Also, please CC linux-pm at lists.linux-foundation.org on patches related to 
this conversion.

Cheers,
FJP
