[PATCH 5/5] Fix mute key for W series Thinkpads

[Jerone Young]

commit 9d63fec73490e9705789357854ddeb9ee87a8baa

    ACPI: Add Thinkpad W500, W700, & W700ds 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
    T61 already on the white list.
