Runtime power management in i2c-hid brings lots of issues, such as: - When transitioning from display manager to desktop session, i2c-hid was closed and opened, so the device was set to SLEEP and ON in a short period. Vendors confirmed that their devices can't handle fast ON/SLEEP command because Windows doesn't have this behavior. - When rebooting, i2c-hid was closed, and the driver core put the device back to full power before shutdown. This behavior also triggers a quick SLEEP and ON commands that some devices can't handle, renders an unusable touchpad after reboot. - Most importantly, my power meter reports little to none energy saving when i2c-hid is runtime suspended. So let's remove runtime power management since there is no actual benefit.
