Ilya A. Volynets-Evenbakh ac122bb64b ACPI: dock: add access to ACPI docking station UID
It is useful to know whether your laptop is docked or not,
but it is even more useful to know which docking station it's
docked to. Attached patch adds "uid" file to sysfs.
Tested on Dell Latitude D600 with D/Dock.
Patch is against official 2.6.20 release.

Len Brown f52fd66d2e ACPI: clean up ACPI_MODULE_NAME() use
cosmetic only

Make "module name" actually match the file name.
Invoke with ';' as leaving it off confuses Lindent and gcc doesn't care.
Fix indentation where Lindent did get confused.

Send a uevent to indicate a device change whenever we dock or
undock, so that userspace may now check the dock status via sysfs.

brandon@ifup.org c80fdbe81a ACPI: dock: Add a docked sysfs file to the dock driver.
Add 2 sysfs files for user interface.
1) docked - 1/0 (read only) - indicates whether the software believes the
laptop is docked in a docking station.
2) undock - (write only) - writing to this file causes the software to
initiate an undock request to the firmware.

http://bugzilla.kernel.org/show_bug.cgi?id=7303

Use a mutex instead of a spinlock for locking the
hotplug list because we need to call into the ACPI
subsystem which might sleep.

Kristen Carlson Accardi 5669021e40 PCI: docking station: remove dock uevents
Remove uevent dock notifications.  There are no consumers
of these events at present, and uevents are likely not the
correct way to send this type of event anyway.

Until I get some kind of idea if anyone in userspace cares
about dock events, I will just not send any.

Kristen Accardi a5e1b94008 ACPI: dock driver
Create a driver which lives in the acpi subsystem to handle dock events.
This driver is not an "ACPI" driver, because acpi drivers require that the
object be present when the driver is loaded.
