This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit 81422e672f8181d7ad1ee6c60c723aac649f538f ]
According to Documentation/power/devices.txt
The driver should not use device_set_wakeup_enable() which is the policy
for user to decide.
Using device_init_wakeup() to initialize dev->power.should_wakeup and
dev->power.can_wakeup on driver initialization.
And use device_may_wakeup() on suspend to decide if WoL function should
be enabled on NIC.
