    ASoC: rt5682: Disable irq on shutdown · 47bcb1c7
    Stephen Boyd authored
    We cancel the work queues, and reset the device on shutdown, but the irq
    isn't disabled so the work queues could be queued again. Let's disable
    the irq during shutdown so that we don't have to worry about this device
    trying to do anything anymore. This fixes a problem seen where the i2c
    bus is shutdown at reboot but this device irq still comes in and tries
    to make another i2c transaction when the bus doesn't work.
