    Subject[PATCH v4 6/7] acpi/x86: s2idle: Add a quirk for Lenovo Slim 7 Pro 14ARH7
    Date
    Lenovo Slim 7 Pro 14ARH7 has a sporadically non-functional keyboard
    when resuming from s2idle. This is caused by some missing calls to the
    EC that don't occur in the AMD codepath but only in the Microsoft codepath.

    Add the system to the quirk list to force Microsoft codepath.
