    ALSA: hda - Fix mute led GPIO on HP dv-series notebooks · d38cce70
    Kunal Gangakhedkar authored
    On my laptop (HP dv6-1110ax), there are no OEM strings in SMBIOS of type
    "HP_Mute_LED*". Hence, the GPIO for the mute button LED doesn't get set
    properly. I didn't find the strings in my cousin's laptop (HP dv9500t CTO)
    either.
    
    As per the documentation of find_mute_led_gpio(), these strings occur
    in HP B-series systems - so, before scanning the SMBIOS strings, we need to
    check if we're dealing with a B-series system.
    Need to get confirmation from HP if this logic takes care of all the
    systems. I'm trying to poke a friend there.
