    Subject[PATCH 5.10 077/146] platform/x86: thinkpad_acpi: Add X1 Carbon Gen 9 second fan support
    Date
    From: Til Jasper Ullrich <tju@tju.me>

    [ Upstream commit c0e0436cb4f6627146acdae8c77828f18db01151 ]

    The X1 Carbon Gen 9 uses two fans instead of one like the previous
    generation. This adds support for the second fan. It has been tested
    on my X1 Carbon Gen 9 (20XXS00100) and works fine.
