I guess this replaces the patch titled "drivers: phy: exynos4x12-phy:
fix HSIC1 power on/off sequence"

Tested on ODROID-U2. Seems to be working as well as the previous patch:
- Internal SMSC hub works on boot and after reboot, tested with USB mouse
- Internal SMSC ethernet device works on boot, but disappears upon
reboot. (same as previous patch, also reproduced by Marek)

Thanks,
Daniel
