[PATCH] Some Samsung laptops with Fn+Fx key release not working

    Some new Samsung laptops doesn't send key-release signal of the 
    volume key to the OS, it's quite hard to change the volume by 
    using Fn+Fx, so I decode the DMI and add several samsung machines
    to the forced_release_keys table in order to fixed this problem.
    
    DMI (only a part):
    # dmidecode
... 
Handle 0x0001, DMI type 1, 27 bytes

    input/keyboard: Some Samsung laptops with Fn+Fx key release not working
    
    Some new Samsung laptops doesn't send key-release signal to the Operating
    System when we click on Fn+F[6-8], so we have to force it to release immedi-
    ately after receiving the key-press signal.
