Subject: PM: wakeup: expose pm_wakeup_pending to modules
X-Git-Tag: v6.6.17~7481^2^3~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=55266546f45dcc9284ca93f4fa3f6693d30ea8ce;p=platform%2Fkernel%2Flinux-rpi.git

PM: wakeup: expose pm_wakeup_pending to modules

intel_pch_thermal driver needs a long delay to cool itself (60 seconds
in maximum) during suspend. When a wakeup event occures during the
delay, it is better for the intel_pch_thermal driver to detect this and
quit cooling because the suspend is likely to abort anyway.

Thus expose pm_wakeup_pending to modules so that intel_pch_thermal
driver can be aware of the wakeup events.
