2007-04-21ACPI: thinkpad-acpi: improve thinkpad detectionHenrique de Moraes Holschuh
Improve the detection of ThinkPads, so as to reduce the chances of false positives. Since this could potentially add false negatives on the very old models, add a module parameter to force the detection of a thinkpad.

2007-04-21ACPI: thinkpad-acpi: uncouple subdriver init from ibms structHenrique de Moraes Holschuh
Move the .init method from ibms struct to another struct, and use a list head to control which subdrivers have been activated. This allows us to have the subdriver init methods marked __init, saving quite a lot of .text size, and even a bit of .data size as some data can now be made __initdata.

2007-04-21ACPI: thinkpad-acpi: clean up probing and move init to subdriversHenrique de Moraes Holschuh
Move most of the probing code to its own function, and most of the subdriver-specific init code into subdriver init functions. This allows us to not define pci_handle unless the dock subdriver is enabled, as well. This patch causes a minor userland interface change: if a subdriver doesn't detect a capability, /proc entries for it are not created anymore (as opposed to a /proc entry that just returned "unsupported").

2007-03-30ACPI: ibm-acpi: rename driver to thinkpad-acpiHenrique de Moraes Holschuh
Rename the ibm-acpi driver to thinkpad-acpi. ThinkPads are not even made by IBM anymore, so it is high time to rename the driver... The name thinkpad-acpi was used sometime ago by a thinkpad-specific hotkey driver by Erik Rigtorp, around the 2.6.8-2.6.10 time frame. The driver apparently never got merged into mainline (it did make some trips through -mm). ibm-acpi was merged soon after, making its debut in 2.6.10. The reuse of the thinkpad-acpi name shouldn't be a problem as far as user confusion goes, as Erik's thinkpad-acpi apparently didn't get widespread use in the Linux ThinkPad community and most hits for thinkpad-acpi in google point to ibm-acpi anyway. Erik, if you read this, please consider the reuse of the thinkpad-acpi name as a compliment to your effort to make ThinkPads more useful to all of us.

2007-02-20backlight: Separate backlight properties from backlight ops pointersRichard Purdie

2007-02-20backlight: Fix external uses of backlight internal semaphoreRichard Purdie
backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2007-02-20backlight: Remove unneeded owner fieldRichard Purdie
Remove uneeded owner field from backlight_properties structure. Nothing uses it and it is unlikely that it will ever be used.
