2007-02-20backlight: Separate backlight properties from backlight ops pointersRichard Purdie
Per device data such as brightness belongs to the indivdual device and should therefore be separate from the the backlight operation function pointers. This patch splits the two types of data and allows simplifcation of some code. 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. The backlight class uses other means to ensure that nothing references unloaded code. Based on a patch from Dmitry Torokhov <dtor@insightbb.com> Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

2007-02-12ACPI: fix acpi_driver.name usageLen Brown
It was erroneously used as a description rather than a name. ie. turn this: lenb@se7525gp2:/sys> ls bus/acpi/drivers ACPI AC Adapter Driver ACPI Embedded Controller Driver ACPI Power Resource Driver ACPI Battery Driver ACPI Fan Driver ACPI Processor Driver ACPI Button Driver ACPI PCI Interrupt Link Driver ACPI Thermal Zone Driver ACPI container driver ACPI PCI Root Bridge Driver hpet into this: lenb@se7525gp2:~> ls /sys/bus/acpi/drivers ac battery button container ec fan hpet pci_link pci_root power processor thermal Signed-off-by: Len Brown <len.brown@intel.com>
2007-02-12ACPI: clean up ACPI_MODULE_NAME() useLen Brown
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. Signed-off-by: Len Brown <len.brown@intel.com>

2006-12-20ACPI: Implement acpi_video_get_next_level()Thomas Tuttle
acpi_video_get_next_level was supposed to implement an algorithm to select a new brightness level based on the old brightness level of an ACPI video device, but it simply says "/* Fix me */" and returns the current brightness. This patch implements acpi_video_get_next_level properly. It had to change a few constants at the top of the file because they were (apparently) wrong, but it appears to work on my Dell Inspiron e1405 (with BIOS A05 only--BIOS A04 doesn't seem to send ACPI video hotkey events).

2006-12-15ACPI: Set fake hid for non-PNPID ACPI devicesZhang Rui
We do this mainly because: 1. hid is used to match ACPI devices and drivers. .match method which is incompatible to driver model can be deleted from acpi_driver.ops then. 2. As the .uevent method mark ACPI drivers by PNPID, fake hid is set to non-PNPID devices so that udev script can load the right ACPI driver by looking for "HWID = " or "COMPTID = ".

2005-08-04[ACPI] acpi_remove_notify_handler() on video driver unloadKarol Kozimor
The video driver doesn't properly remove all the notify handlers on module unload. This has a side effect of subdevices failing to register on module reload, but sudden death looms if the handlers trigger after the module is unloaded.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
