powerpc: Remove asm/prom.h from all files that don't need it

2022-05-08T12:15:04Z

Several files include asm/prom.h for no reason. Clean it up.

treewide: Add SPDX license identifier for missed files

2019-05-21T08:50:45Z

Add SPDX license identifiers to all files which: - Have no license information of any form - Have EXPORT_.*_SYMBOL_GPL inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

powerpc: Fix old-style function definition

Fix warnings such as: arch/powerpc/platforms/powermac/backlight.c: In function ‘pmac_backlight_get_legacy_brightness’: arch/powerpc/platforms/powermac/backlight.c:189:5: error: old-style function definition [-Werror=old-style-definition] int pmac_backlight_get_legacy_brightness() ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Mathieu Malaterre Signed-off-by: Michael Ellerman

powerpc: add export.h to files making use of EXPORT_SYMBOL

2011-10-31T23:30:37Z

With module.h being implicitly everywhere via device.h, the absence of explicitly including something for EXPORT_SYMBOL went unnoticed. Since we are heading to fix things up and clean module.h from the device.h file, we need to explicitly include these files now. Signed-off-by: Paul Gortmaker

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

WorkQueue: Fix up arch-specific work items where possible

2006-12-05T19:36:26Z

Fix up arch-specific work items where possible to use the new work_struct and delayed_work structs. Three places that enqueue bits of their stack and then return have been marked with #error as this is not permitted. Signed-Off-By: David Howells
