Subject: panasonic-laptop: Use struct dev_pm_ops for power management
X-Git-Tag: next-20120724~40^2~6^2~9
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a7377419624c31d71e35485251f8548c728d5999;p=karo-tx-linux.git

panasonic-laptop: Use struct dev_pm_ops for power management

Make the panasonic-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.
