  • 599a52d12   backlight: Separate backlight properties from backlight ops pointers ... Browse Code »

    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.

  • 28ee086d5   backlight: Fix external uses of backlight internal semaphore ... Browse Code »

    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.

    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

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • 4b87361d4   USB: u132-hcd/ftdi-elan: add support for Option GT 3G Quad card ... Browse Code »

    ELAN's U132 is a USB to CardBus OHCI controller adapter,
    designed specifically for CardBus 3G data cards to
    function in machines without a CardBus slot.
    The "ftdi-elan" module is a USB client driver, that detects
    a supported CardBus OHCI controller plugged into the
    U132 adapter and thereafter provides the conduit for
    for access by the "u132-hcd" module.
    The "u132-hcd" module is a (cut-down OHCI) host controller
    that supports a single OHCI function of the CardBus
    card inserted into the U132 adapter.

    The problem with the initial implementation is that when
    the CardBus card inserted into the U132 adapter has multiple
    functions (and a CardBus card can support up to 4 functions),
    it was the first function that was arbitrarily choosen.

    The first batch of 3G cards tested, like the Merlin Qualcomm
    V620, have two functions each supporting a seperate USB OHCI
    host controller, of which it was that first function that is
    wired up to the 3G modem.

    Then along comes the Vodafone Mobile Connect 3G/GPRS data card,
    aka "Option GT 3G Quad" as printed on it's rear or "Option N.V.
    GlobeTrotter Fusion Quad Lite" as read with "lspci -v". And it
    has the meaningful functionality in the second CardBus function.

    That presents a problem because it was the "ftdi-elan" module
    alone that knows how to communicate to the embedded CardBus slot
    and the "u132-hcd" module alone that knows how to access the
    pcmcia configuration and CardBus accessible memory space. And
    of course, the information about attached (internally hardwired)
    devices is contained within USB configuration embedded somewhere
    within the CardBus card.

    If only the "u132-hcd" module probe() interface could return a
    result code that propagated back to the instigating function
    platform_device_register() then the "ftdi-elan" module could
    try an alternative CardBus function. However in spite of
    the recent changes to the drivers/base/ routines that moved
    device_attach() from bus_add_device() to bus_attach_device()
    both of those routines lose the "failed to attach" 0 result
    code and thus the calling routine, namely device_add() is
    incapable of propaging the "failed to attach" condition back
    to platform_device_add() and consequently back to the caller
    of platform_device_register()

    Experiments show that patching bus_attach_device() to return
    ENODEV fails with the kernel locking up very early during
    boot. But, however, if the patch is restricted to calls from
    platform_device_add() then it does seem to work.

    Unfortunately, until the kernel's drivers/base is properly
    modified to propagate -ENODEV back to the caller of
    platform_device_register(), it is necessary to "fix" the
    "ftdi-elan" module by importing knowledge from the
    "u132-hcd" module. This is the reason for the duplicated
    functionality introduced in this patch.

    This patch set adds generic abstract layer support for acpi video driver to
    have generic user interface to control backlight and output switch control by
    leveraging the existing backlight sysfs class driver, and by adding a new
    video output sysfs class driver.

    This patch:

    Add dev argument for backlight_device_register to link the class device to
    real device object. The platform specific driver should find a way to get the
    real device object for their video device.

    And then go through and reinstate those cases where code is casting pointers

    And then drop a few hunks which conflicted with outstanding work.
