HID: picoLCD: prevent NULL pointer dereferences Driver code expects to get access to struct picolcd_data from hiddev and is not prepared to find a NULL pointer there. Most prominent candidate to trip on it is picolcd_fb_deferred_io(). Delay removing struct picolcd_data from hiddev until all sub-devices have been unregistered.
