Subject: [PATCH missing/21] classmate-laptop: Use struct dev_pm_ops for power management

From: Rafael J. Wysocki <rjw@...k.pl>

Make the classmate-laptop driver define its PM callbacks through
a struct dev_pm_ops object rather than by using legacy PM hooks
in struct acpi_device_ops.

Signed-off-by: Rafael J. Wysocki <rjw@...k.pl>

Hi all,

I overlooked the classmate-laptop driver in the ACPI conversion to PM
handling based on struct dev_pm_ops, so this one should go after [17/21] and
the next patches should be renumbered.

Thanks,
Rafael
