Subject: [PATCH 4.19 058/170] r8169: fix WoL device wakeup enable

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Heiner Kallweit <hkallweit1@...il.com>

[ Upstream commit 3bd8264511035dc97c902f03fa9f1d07f95f8f62 ]

In rtl8169_runtime_resume() we configure WoL but don't set the device
to wakeup-enabled. This prevents PME generation once the cable is
re-plugged. Fix this by moving the call to device_set_wakeup_enable()
to __rtl8169_set_wol().
