2009-01-08backlight: hp680_bl - Use platform_device_register_simple()Akinobu Mita
Use platform_device_register_simple() and also fix error handling when platform_device_alloc() fails (hp680_bl_driver is left registered). Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>

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: Minor code cleanups for hp680_bl.cRichard Purdie
Since people use this code as an example, clean it up to to use platform_*_drvdata instead of a global variable. 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>

Fix breakage from commit 519ab5f2be65b72cf12ae99c89752bbe79b44df6 which didn't update all references to backlight_device_register causing compile failures. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Len Brown <len.brown@intel.com>
2006-12-08[PATCH] backlight: do not power off backlight when unregisteringHenrique de Moraes Holschuh
ACPI drivers like ibm-acpi are moving to the backlight sysfs infrastructure. During ibm-acpi testing, I have noticed that backlight_device_unregister() sets the display brightness and power to zero. This causes the display to be dimmed on ibm-acpi module removal. It will affect all other ACPI drivers that are being converted to use the backlight class, as well. It also affects a number of framebuffer devices that are used on desktops and laptops which might also not want such behaviour. Since working around this behaviour requires undesireable hacks, Richard Purdie decided that we would be better off reverting the changes in the sysfs class, and adding the code to dim and power off the backlight device to the drivers that want it. This patch is my attempt to do so. Patch against latest linux-2.6.git. Changes untested, as I lack the required hardware. Still, they are trivial enough that, apart from typos, there is little chance of getting them wrong.

2006-06-27[PATCH] spin/rwlock init cleanupsIngo Molnar
locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-03-31[PATCH] backlight: HP Jornada 680 Backlight driver updates/fixesRichard Purdie
Updates to the HP Jornada 680 Backlight driver: - Correct the suspend/resume functions so the driver compiles (SUSPEND_POWER_DOWN/RESUME_POWER_ON no longer exist). - Convert the driver to match the recent platform device changes. - Replace the unsafe static struct platform_device with dynamic allocation. - Convert the driver to the new backlight code. This has not been tested on a device due to lack of hardware but wouldn't compile beforehand.
