[PATCH 2/5] Fix mute key for X200 series Thinkpads

[Jerone Young]

commit 1e6df1b8003388c084d0751e88f7d81c69eba0cf

    ACPI: Add Thinkpad X200, X200s, X200t to OSI(Linux) white-list
    
    acpi_osi=Linux helps the mute button work properly by sending Linux
    a mute key press. This is the same behavior as seen with the Thinkpad
    X61 already on the white list.
