Signed-off-by: Charles Keepax --- Changes since v5: - Pass a struct device rather than acpi_device to i2c_acpi_get_irq, note this is more awkward than I would have liked as I am very unconvinced that adev->dev can actually be passed to ACPI_COMPANION. If anyone can answer that for sure that would be very helpful.
