Subject: PCI/PM: Use pm_wakeup_event() directly for reporting wakeup events
X-Git-Tag: v3.0~2083^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b6e335aeeb114dccb07eaa09e8b62ff9510cf745;p=platform%2Fkernel%2Flinux-amlogic.git

PCI/PM: Use pm_wakeup_event() directly for reporting wakeup events

After recent changes related to wakeup events pm_wakeup_event()
automatically checks if the given device is configured to signal wakeup,
so pci_wakeup_event() may be a static inline function calling
pm_wakeup_event() directly.
