Kishon writes:
New Features
============
*) Add driver for USB PHYs on sun9i
*) Add driver for USB PHY on dm816x
*) Modified exynos5-usbdrd driver to add support for Exynos5433 SoC
Fixes
=====
*) Fix power_on/power_off failure paths in some drivers
*) Make miphy365x use generic PHY type constants
*) Fix build errors due to missing export symbols in qcom-ufs driver
*) Make all the functions return proper error values
Cleanups
========
*) use PTR_ERR_OR_ZERO to simplify code
*) use devm_kcalloc instead of devm_kzalloc with multiply
*) remove un-necessary ifdef CONFIG_OF
