S-Pen models (SM-P550, SM-P555) may invert the touchscreen Y-axis after flashing and running TWRP. To fix it, flash stock Android Recovery and run it at least once.

I fail to understand this change. The correct way to fix this is to implement extcon/otg power support in the charger driver. Forcing host is wrong and usb won't get power anyway.
