Subject: [PATCH] olpc-xo15-sci: Use struct dev_pm_ops for power management

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

Make the OLPC XO15 SCI driver define its resume callback through
a struct dev_pm_ops object rather than by using a legacy PM hook
in struct acpi_device_ops.

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

This patch was missing from my patchset converting ACPI do the PM handling
based on struct dev_pm_ops.

If there are no objections, I'll add it to the pm-acpi branch of the
linux-pm.git tree so that it goes in along with the other changes in that
area.

Thanks,
Rafael
