git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more ACPI and power management updates from Rafael Wysocki: "These are regression fixes (leds-gpio, ACPI backlight driver, operating performance points library, ACPI device enumeration messages, cpupower tool), other bug fixes (ACPI EC driver, ACPI device PM), some cleanups in the operating performance points (OPP) framework, continuation of CONFIG_PM_RUNTIME elimination, a couple of minor intel_pstate driver changes, a new MAINTAINERS entry for it and an ACPI fan driver change needed for better support of thermal management in user space. Specifics: - Fix a regression in leds-gpio introduced by a recent commit that inadvertently changed the name of one of the properties used by the driver (Fabio Estevam). - Fix a regression in the ACPI backlight driver introduced by a recent fix that missed one special case that had to be taken into account (Aaron Lu). - Drop the level of some new kernel messages from the ACPI core introduced by a recent commit to KERN_DEBUG which they should have used from the start and drop some other unuseful KERN_ERR messages printed by ACPI (Rafael J Wysocki). - Revert an incorrect commit modifying the cpupower tool (Prarit Bhargava). - Fix two regressions introduced by recent commits in the OPP library and clean up some existing minor issues in that code (Viresh Kumar). - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the tree (or drop it where that can be done) in order to make it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf Hansson, Ludovic Desroches). There will be one more "CONFIG_PM_RUNTIME removal" batch after this one, because some new uses of it have been introduced during the current merge window, but that should be sufficient to finally get rid of it. - Make the ACPI EC driver more robust against race conditions related to GPE handler installation failures (Lv Zheng). - Prevent the ACPI device PM core code from attempting to disable GPEs that it has not enabled which confuses ACPICA and makes it report errors unnecessarily (Rafael J Wysocki). - Add a "force" command line switch to the intel_pstate driver to make it possible to override the blacklisting of some systems in that driver if needed (Ethan Zhao). - Improve intel_pstate code documentation and add a MAINTAINERS entry for it (Kristen Carlson Accardi). - Make the ACPI fan driver create cooling device interfaces witn names that reflect the IDs of the ACPI device objects they are associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B"). That's necessary for user space thermal management tools to be able to connect the fans with the parts of the system they are supposed to be cooling properly.

2014-12-16[media] vino/saa7191: move to staging in preparation for removalHans Verkuil
These drivers haven't been tested in a long, long time. The hardware is ancient and hopelessly obsolete. These drivers also need to be converted to newer media frameworks but due to the lack of hardware that's going to be impossible. So these drivers are a prime candidate for removal. If someone is interested in working on these drivers to prevent their removal, then please contact the linux-media mailinglist.

2014-11-25[media] vb2-dma-sg: move dma_(un)map_sg hereHans Verkuil
This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put memops of videobuf2-dma-sg.c and adds dma_sync_sg_for_device/cpu to the prepare/finish memops. Now that vb2-dma-sg will sync the buffers for you in the prepare/finish memops we can drop that from the drivers that use dma-sg. For the solo6x10 driver that was a bit more involved because it needs to copy JPEG or MPEG headers to the buffer before returning it to userspace, and that cannot be done in the old place since the buffer there is still setup for DMA access, not for CPU access. However, the buf_finish op is the ideal place to do this. By the time buf_finish is called the buffer is available for CPU access, so copying to the buffer is fine.

2014-11-14[media] platform: Make use of media_bus_format enumBoris BREZILLON
In order to have subsytem agnostic media bus format definitions we've moved media bus definition to include/uapi/linux/media-bus-format.h and prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT. Reference new definitions in all platform drivers.

2014-11-11[media] media: davinci: vpbe: missing clk_putSudip Mukherjee
we are getting struct clk using clk_get before calling clk_prepare_enable. but if clk_prepare_enable fails, then we are jumping to fail_mutex_unlock where we are just unlocking the mutex, but we are not freeing the clock source. this patch just adds a call to clk_put before jumping to fail_mutex_unlock.

2014-11-11[media] vivid: add test array controlsHans Verkuil
Add array controls to test support for such controls. There is one array with just one element, one 8x16 matrix control and one 4 dimensional 2x3x4x5 control. This makes it possible to experiment with such controls without requiring hard-to-get hardware.

2014-10-30[media] ti-fpe: LLVMLinux: Remove nested function from ti-vpeBehan Webster
Replace the use of nested functions where a normal function will suffice. Nested functions are not liked by upstream kernel developers in general. Their use breaks the use of clang as a compiler, and doesn't make the code any better. This code now works for both gcc and clang.
