====================
Fixes for dwmac-sun8i suspend/resume

This series fixes issues preventing dwmac-sun8i from working after a
suspend/resume cycle. Those issues include the PHY being left powered
off, the MAC syscon configuration being reset, and the reference to the
reset controller being improperly dropped. They also fix related issues
in probe error handling and driver removal.
