    The active_high LED of my Wistron DNMA-92 is still being recognized as
    active_low on 4.7.6 mainline. When I was preparing my former commit
    0f9edcdd ("ath9k: Fix LED polarity for some Mini PCI AR9220 MB92
    cards.") to fix that I must have somehow messed up with testing, because
    I tested the final version of that patch before sending it, and it was
    apparently working; but now it is not working on 4.7.6 mainline.
    
    I initially added the PCI_DEVICE_SUB section for 0x0029/0x2096 above the
    PCI_VDEVICE section for 0x0029; but then I moved the former below the
    latter after seeing how 0x002A sections were sorted in the file.
    
    This turned out to be wrong: if a generic PCI_VDEVICE entry (that has
    both subvendor and subdevice IDs set to PCI_ANY_ID) is put before a more
    specific one (PCI_DEVICE_SUB), then the generic PCI_VDEVICE entry will
    match first and will be used.
    
    With this patch, 0x0029/0x2096 has finally got active_high LED on 4.7.6.
    
    While I'm at it, let's fix 0x002A too by also moving its generic definition
    below its specific ones.
