[RFT][PATCH 00/12] change drivers power management to use dev_pm_ops

[Shuah Khan]

Change drivers to register pm ops using dev_pm_ops instead of legacy pm_ops.
.pm hooks call existing legacy suspend and resume interfaces by passing in
the right pm state. Bus drivers suspend and resume routines call .pm driver
hooks if found.

[RFT][PATCH 04/12] drivers/macintosh/adb: change platform power management to use dev_pm_ops

[Shuah Khan]

Change adb platform driver to register pm ops using dev_pm_ops instead of
legacy pm_ops. .pm hooks call existing legacy suspend and resume interfaces
by passing in the right pm state.
