backlight: Convert from struct class_device to struct device

2007-07-16T00:20:23Z

Convert the backlight and LCD classes from struct class_device to struct device since class_device is scheduled for removal. One nasty API break is the backlight power attribute has had to be renamed to bl_power and the LCD power attribute has had to be renamed to lcd_power since the original names clash with the core. I can't see a way around this. Signed-off-by: Richard Purdie Acked-by: Greg Kroah-Hartman

sysfs: kill unnecessary attribute->owner

2007-07-11T23:09:06Z

sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

backlight: Separate backlight properties from backlight ops pointers

2007-02-20T09:26:53Z

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

backlight: Fix external uses of backlight internal semaphore

2007-02-20T08:38:45Z

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

backlight: Remove excessive (un)likelys

2007-02-20T08:38:44Z

Remove excessive numbers of (un)likely()s in the backlight core. There are no hot paths in this code so rely on compiler to do the right thing. Signed-off-by: Dmitry Torokhov Signed-off-by: Richard Purdie

backlight: Fix error handling

Fix error handling when registering new device Signed-off-by: Dmitry Torokhov Signed-off-by: Richard Purdie

[PATCH] backlight: lcd: Remove dependenct from the framebuffer layer

2006-12-08T16:29:07Z

The backlight layer should be independent from the framebuffer layer. It can use the services offered by the framebuffer, but its absence should not prevent the backlight/lcd layer from functioning.
