Add i2c_hid_shutdown for i2c-hid driver to send suspend cmd & free irq before device shutdown. Some HW design (i.e. Umaro, a chromebook model) is that the power to i2c hid device won't down after device shutdown. Also the i2c-hid driver do not send suspend cmd to the hid i2c device and free its irq before shutdown.So if We touch the touchscreen or some other i2c hid device, the power consumtion will be go up even when the device is in shutdown state. Though the root cause maybe a HW issue. But it seems that it is a good pratice to set power sleep for i2c-hid device before shutdown.
