backlight: add backlight type

2011-03-23T00:43:59Z

There may be multiple ways of controlling the backlight on a given machine. Allow drivers to expose the type of interface they are providing, making it possible for userspace to make appropriate policy decisions.

Merge branch 'master' into for-next

2010-12-22T17:57:02Z

Conflicts: MAINTAINERS arch/arm/mach-omap2/pm24xx.c drivers/scsi/bfa/bfa_fcpim.c Needed to update to apply fixes for which the old branch was too outdated.

toshiba_acpi.c: Add key_entry for a lone FN keypress

2010-11-24T16:59:37Z

A lone FN key press on a Toshiba Portégé R700 without another key in conjunction results in an ACPI event and a spurious error message on the console. Add a key entry to map this event to a KEY_FN keypress. This prevents the console message. Signed-off-by: Jon Dowland Signed-off-by: Matthew Garrett

backlight: constify backlight_ops

2010-11-16T13:14:02Z

backlight_device_register has been expecting a const "ops" argument, and using it as such, since 9905a43b2d563e6f89e4c63c4278ada03f2ebb14. Let's make the remaining backlight_ops instances const. Inspired by hunks of the grsecurity patch, updated for newer kernels. Signed-off-by: Lionel Debroux Acked-by: Ingo Molnar Signed-off-by: Jiri Kosina

toshiba-acpi - switch to using sparse keymap

2010-10-21T13:36:43Z

Instead of implementing its own version of keymap hanlding switch over to using sparse keymap library. Also, install notify handler only after we allocated input device, otherwise we may risk getting event too early and crash. Similarly, notify handler should be removed before we unregister input device. Signed-off-by: Dmitry Torokhov Signed-off-by: Matthew Garrett

toshiba-acpi: Add support for Toshiba Illumination.

2010-08-03T13:49:10Z

Add support for Toshiba Illumination. This is a set of LEDs installed on some Toshiba laptops. It is controlled through ACPI, the commands has been found through reverse engineering. It has been tested on a Toshiba Qosmio G50-122. Signed-off-by: Pierre Ducroquet Signed-off-by: Matthew Garrett

toshiba_acpi: rename add_device() and remove_device() to create_toshiba_proc_entries() and remove_toshiba_proc_entries()

2010-08-03T13:49:03Z

To improve readability rename add_device() to create_toshiba_proc_entries() and rename remove_device() to remove_toshiba_proc_entries(). Signed-off-by: Axel Lin Cc: Matthew Garrett Cc: Márton Németh Signed-off-by: Andrew Morton Signed-off-by: Matthew Garrett

toshiba_acpi: make remove_device() and add_device() void

2010-08-03T13:49:02Z

remove_device() and add_device() are not related to ACPI APIs, it does not make sense to return acpi_status for both functions. Current implementation of add_device() always AE_OK, thus the return value checking for add_device() always return false for ACPI_FAILURE(status). This patch makes add_device() to be void and remove the unnecessary return value checking. remove_proc_entry() won't fail, thus change remove_device() to be void.

toshiba-acpi: Add an extra couple of keys

2010-08-03T13:48:53Z

Thomas Bächler reports that his machine generates two keycodes for zooming in and out. Add these to the default keymap. Signed-off-by: Matthew Garrett Cc: Thomas Bächler

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32Z

percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
