ACPI device ID arrays normally don't need to be written to as they're only ever read. The common usage -- embedding pointers to acpi_device_id arrays in other data structures -- reference them as 'const', e.g. as in struct acpi_driver / acpi_scan_handler / device_driver. The matchers are taking const pointers, too. So it's only natural, to propose using const arrays. Change the documentation accordingly. Signed-off-by:

Port the backlight selection logic to the new backlight interface selection API. This commit also removes various obsolete pr_xxx messages related to backlight interface selection. These are obsolete because they assume there is only a vendor or acpi backlight driver and no other choice. Also they are not necessary, if the user wants to know which backlight interfaces are registered a simple "ls /sys/class/backlight" suffices. Signed-off-by:

It is possible for a native backlight driver to load while acpi_video_register is running, which may lead to acpi_video_unregister_backlight being called while acpi_video_register is running and the 2 racing against eachother. The register_count variable protects against this, but not in a thread safe manner, this commit adds locking to make this thread safe. Signed-off-by:

When builtin there is no guarantee in which order module_init functions are run, so acpi_video_register() may get called from the i915 driver (if it is also builtin) before acpi_video_init() gets called, resulting in the dmi quirks not yet being parsed. This commit moves the dmi_check_system() call to acpi_video_register(), so that we can be sure the dmi quirks have always been applied before probing. Signed-off-by:

Move the unregistering of the acpi backlight interface on registering of a native backlight from video.c to video_detect.c where it belongs. Note this removes support for re-registering the acpi backlight interface when the native interface goes away. In practice this never happens and it needlessly complicates the code. Signed-off-by:

Most of the patch is moving the dmi quirks for forcing use of the acpi-video / the native backlight interface to video_detect.c. What remains is a nice cleanup. Signed-off-by:

This results in a nice cleanup, as we can replace the complicated logic from should_ignore_backlight_request() with a simple check for the type being native. Signed-off-by:

Make acpi_video_set_dmi_backlight_type() call acpi_video_unregister_backlight() when the new dmi quirk results in the desired backlight interface being of a type other then acpi_backlight_video. This avoid the need for the second if in the following construction which is currently found in many platform/x86 drivers: if (prefer_vendor_quirk) acpi_video_dmi_promote_vendor(); if (!acpi_video_backlight_support()) acpi_video_unregister_backlight() This second if-block will be removed from the platform drivers as part of their conversion to the new backlight interface selection API.

Currently we have 2 kernel commandline options + dmi-quirks in 3 places all interacting (in interesting ways) to select which which backlight interface to use. On the commandline we've acpi_backlight=[video|vendor] and video.use_native_backlight=[0|1]. DMI quirks we have in acpi/video-detect.c, acpi/video.c and drivers/platform/x86/*.c . This commit is the first step to cleaning this up, replacing the 2 cmdline options with just acpi_backlight=[video|vendor|native|none], and adds a new API to video_detect.c to reflect this. Follow up commits will also move other related code, like unregistering the acpi_video backlight interface if it was registered before other drivers which take priority over it are loaded, to video_detect.c where this logic really belongs.

This is a preparation patch for the backlight interface selection logic cleanup, there are 2 reasons to not always build the video_detect code into the kernel: 1) In order for the video_detect.c to also deal with / select native backlight interfaces on win8 systems, instead of doing this in video.c where it does not belong, video_detect.c needs to call into the backlight class code. Which cannot be done if it is builtin and the blacklight class is not. 2) Currently all the platform/x86 drivers which have quirks to prefer the vendor driver over acpi-video call acpi_video_unregister_backlight() to remove the acpi-video backlight interface, this logic really belongs in video_detect.c, which will cause video_detect.c to depend on symbols of video.c and video.c already depends on video_detect.c symbols, so they really need to be a single module. Note that this commits make 2 changes so as to maintain 100% kernel commandline compatibility: 1) The __setup call for the acpi_backlight= handling is moved to acpi/util.c as __setup may only be used by code which is alwasy builtin 2) video.c is renamed to acpi_video.c so that it can be combined with video_detect.c into video.ko This commit also makes changes to drivers/platform/x86/Kconfig to ensure that drivers which use acpi_video_backlight_support() from video_detect.c, will not be built-in when acpi_video is not built in. This also changes some "select" uses to "depends on" to avoid dependency loops. Signed-off-by:

acpi_osi_is_win8 needs access to acpi_gbl_osi_data which is not exported, so move it to osl.c. Alternatively we could export acpi_gbl_osi_data but that seems undesirable. This allows video_detect.c to be build as a module, besides that acpi_osi_is_win8() is something which does not really belong in video_detect.c in the first place. Signed-off-by:

This allows video_detect.c to be build as a module, this is a preparation patch for the backlight interface selection logic cleanup. Note this commit also causes acpi_is_video_device() to always be build indepedent of CONFIG_ACPI_VIDEO, as there is no reason to make its building depend on CONFIG_ACPI_VIDEO. Signed-off-by:
