2008-03-18ACPI: Set flag DOCK_UNDOCKING when triggered via sysfsHolger Macht1-0/+1
begin_undock() is only called when triggered via a acpi notify handler (pressing the undock button on the dock station), but complete_undock() is always called after the eject. So if a undock is triggered through a sysfs write, the flag DOCK_UNDOCKING has to be set for the dock station, too. Otherwise this will freeze the system hard.

2007-07-18ACPI: dock: fix oops when _DCK evaluation failsDmitry Torokhov1-4/+4
Data returned by acpi_get_name in acpi_buffer is not acpi_object and therefore should not be cast to it, otherwise we'll get an nice oops trying to print error message. Also print name of the ACPI object corresponding to the docking station and elevate severity of the message printed when _DCK fails to KERN_ERR.

2007-05-10ACPI: dock: add immediate_undock optionKristen Carlson Accardi1-2/+49
Allow the driver to be loaded with an option that will allow userspace to control whether the laptop is ejected immediately when the user presses the button, or only when the syfs undock file is written. if immediate_undock == 1, then when the user presses the undock button, the laptop will send an event to userspace to notify userspace of the undock, but then immediately undock without waiting for userspace. This is the current behavior, and I set this to be the default. if immediate_undock == 0, then when the user presses the undock button, the laptop will send an event to userspace and do nothing. User space can query the "flags" sysfs entry to determine if an undock request has been made by the user (if bit 1 is set). User space will then need to write the undock sysfs entry to complete the undocking process.

2007-05-10ACPI: dock: fix opps after dock driver fails to initializeChuck Ebbert1-0/+7
The driver tests the dock_station pointer for nonnull to check whether it has initialized properly. But in some cases dock_station will be non-null after being freed when driver init fails. Fix by zeroing the pointer after freeing.
