So you want to run a Dell specific ACPI method every time anyone plugs
some NCM class device into a host supporing ACPI? That's going to annoy
the hell out of 99.9997% of the x86, ia64 and arm64 users of this
driver.
Call ACPI once when the driver loads, and only if running on an actual
Dell system where this method is supported. There must be some ACPI
device ID you can match on to know if this method is supported or not?
