+Description:
+ This attribute indicates the full path of ACPI namespace
+ object associated with the device object. For example,
+ \_SB_.PCI0.
+ This file is not present for device objects representing
+ fixed ACPI hardware features (like power and sleep
+ buttons).

+What: /sys/bus/acpi/devices/.../modalias
+Date: July 2007
+Contact: Rafael J. Wysocki <rjw@rjwysocki.net>
+Description:
+ This attribute indicates the PNP IDs of the device object.
+ That is acpi:HHHHHHHH:[CCCCCCC:]. Where each HHHHHHHH or
+ CCCCCCCC contains device object's PNPID (_HID or _CID).

+What: /sys/bus/acpi/devices/.../hid
+Date: April 2005
+Contact: Rafael J. Wysocki <rjw@rjwysocki.net>
+Description:
+ This attribute indicates the hardware ID (_HID) of the
+ device object. For example, PNP0103.
+ This file is present for device objects having the _HID
+ control method.

+Date: December 2006
+Contact: Rafael J. Wysocki <rjw@rjwysocki.net>
+Description:
+ Writing 1 to this attribute will trigger hot removal of
+ this device object. This file exists for every device
+ object that has _EJ0 method.
