my laptop uses a touchpad that needs hid-rmi along with i2c-hid to work.
i2c-hid and hid-rmi can be loaded and unloaded independelty from each
other, however since 34f439e4afcd ("HID: i2c-hid: add runtime PM support")
if I unload hid-rmi and after it I also unload i2c-hid, I get a NULL
pointer dereference.I'll look into this. I can reproduce this easily with i2c-hid + hid-multitouch following your directions.
