    HID: Ignore battery for ELAN touchscreens 2F2C and 4116
    
    [ Upstream commit a3a5a37efba11b7cf1a86abe7bccfbcdb521764e ]
    
    At least ASUS Zenbook 14 (2023) and ASUS Zenbook 14 Pro (2023) are affected.
    
    The touchscreen reports a battery status of 0% and jumps to 1% when a
    stylus is used.
    
    The device ID was added and the battery ignore quirk was enabled for it.
