    Bluetooth: hci_bcm: Add broken-irq dmi blacklist and add Meegopad T08 to it · 2b05393b
    Hans de Goede authored
    The Meegopad T08 hdmi-stick (think Intel computestick) has a brcm43430
    wifi/bt combo chip. The BCM2E90 ACPI device describing the BT part does
    contain a valid ActiveLow GpioInt entry, but the GPIO it points to never
    goes low, so either the IRQ pin is not connected, or the ACPI resource-
    table points to the wrong GPIO.
    
    Eitherway things will not work if we try to use the specified IRQ, this
    commits adds a DMI based broken-irq blacklist and disables use of the IRQ
    and thus also runtime-pm for devices on this list.
    
    This blacklist starts with the the Meegopad T08, fixing bluetooth not
    working on this hdmi-stick. Since this is not a battery powered device
    the loss of runtime-pm is not really an issue.
