Bjorn Helgaas 578b333bfe ACPI: update asus_acpi driver registration to unload on failure
Remove the assumption that acpi_bus_register_driver() returns the number of
devices claimed.  Returning the count is unreliable because devices may be
hot-plugged in the future (admittedly not applicable for this driver).

Since the hardware for this driver is not hot-pluggable, determine whether the
hardware is present by noticing calls to the .add() method.  It would be
better to probe the ACPI namespace for the ASUS HIDs, and load the driver only
when we find one, but ACPI doesn't support that yet.

I don't have an ASUS laptop to test on, but on my HP dl360, it does report the
appropriate error when attempting to load the module:

    $ sudo insmod drivers/acpi/asus_acpi.ko
    insmod: error inserting 'drivers/acpi/asus_acpi.ko': -1 No such device
