Commit Message

Driver added a new dev_pm_ops structure used only if CONFIG_PM is set.
The CONFIG_PM MACRO needed to be moved up in the code to avoid the
compiler warnings. The HUNK to move the location was missing from
the above patch.

Found by kernel test robot by building driver with
CONFIG_PM disabled.

Correct compiler warning
