ACPI: PAD: Pass struct device pointer to acpi_pad_notify()

Browse Source 
Use the struct device pointer to the dev member in the struct
platform_device object representing the platform device used for driver
binding as the last argument of acpi_dev_install_notify_handler() and
accordingly update acpi_pad_notify() to pass that pointer directly to
dev_name() when generating the netlink event.

Since the dev_name() value for an ACPI-enumerated platform device is the
same as the dev_name() value for the dev member of its ACPI companion
object, as per acpi_create_platform_device(), the above code modification
is not expected to cause functionality to change.
