Thomas Renninger 2b2ae7c7f8 ACPI: Do not export hid/modalias sysfs file for ACPI objects without a HID 
Boot and compile tested.
The fact that pnp.ids can now be empty needs testing on some
further machines, though.

This should handle a "modprobe is wrongly called by udev" issue:
https://bugzilla.kernel.org/show_bug.cgi?id=19162

Modaliase files in
/sys/devices/LNXSYSTM:00/
went down from 113 to 71 on my tested system.

This is a sysfs change, but userspace must already be able to handle it.

Also do not fill up pnp.ids list with a "struct hid"
entry. This comment:
     * This generic ID isn't useful for driver binding, but it provides
     * the useful property that "every acpi_device has an ID."
is still half way true:
Best you never touch pnp.ids list directly or make sure it can be empty,
instead use:
char *acpi_device_hid()
which always returns a value ("device" as a dummy if the object
has no hid).
