3.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: hayeswang <[email protected]> commit 10953db8e1a278742ef7e64a3d1491802bcfa98b upstream The link down would occur when reseting PHY. And it would take about 2 ~ 5 seconds from link down to link up. If the delay of pm_schedule_suspend is not long enough, the device would enter runtime_suspend before link up. After link up, the device would wake up and reset PHY again. Then, you would find the driver keep in a loop of runtime_suspend and rumtime_resume.
