    ACPI: video: Loosen strictness of video bus detection code
    
    BugLink: http://bugs.launchpad.net/bugs/333386
    
    Currently a video bus device must (beside other criteria) define _DOD and
    _DOS methods to be considered a video device.
    Some broken BIOSes prevented working backlight control by only defining both
    for one (non-existing bus) and only _DOD for the rest. With this patch in
    place the other bus definitions were considered too and backlight control
    started to work again.

    eeepc-laptop: Prevent a panic when disabling RT2860 wireless when associated
    
    This works around what I think is actually a bug in rt2860sta which is
    triggered when the hardware "disappears" from beneath the driver, i.e. when
    wireless is toggled off via ACPI. It does so by ensuring that the rfkill
    soft-block flag is set before the hardware is disabled.
    
    I do not know whether this patch is required if rt2800pci is in use instead
    of rt2860sta; at the time of submission of this patch, I've not been able to
    test this.

    eeepc-laptop: Properly annote eeepc_enable_camera().
    
    Currently the annotation for function eeepc_enable_camera() is
    __init, and refers to a
    function eeepc_hotk_add() which is non-init. Use __devinit for both
    functions which is
    more appropriate and fixes a section mismatch warning.
    
     We were warned by the following warning:
    
      LD      drivers/platform/x86/built-in.o
    WARNING: drivers/platform/x86/built-in.o(.text+0x12e1): Section
    mismatch in reference from the function eeepc_hotk_add() to the
    function .init.text:eeepc_enable_camera()
    The function eeepc_hotk_add() references
    the function __init eeepc_enable_camera().
    This is often because eeepc_hotk_add lacks a __init
    annotation or the annotation of eeepc_enable_camera is wrong.

commit 497fb54f578efd2b479727bc88d5ef942c0a1e2d

    ACPI / PCI: Fix NULL pointer dereference in acpi_get_pci_dev() (rev. 2)
    
    acpi_get_pci_dev() may be called for a non-PCI device, in which case
    it should return NULL.  However, it assumes that every handle it
    finds in the ACPI CA name space, between given device handle and the
    PCI root bridge handle, corresponds to a PCI-to-PCI bridge with an
    existing secondary bus.  For this reason, when it finds a struct
    pci_dev object corresponding to one of them, it doesn't check if
    its 'subordinate' field is a valid pointer.  This obviously leads to
    a NULL pointer dereference if acpi_get_pci_dev() is called for a
    non-PCI device with a PCI parent which is not a bridge.
    
    To fix this issue make acpi_get_pci_dev() check if pdev->subordinate
    is not NULL for every device it finds on the path between the root
    bridge and the device it's supposed to get to and return NULL if the
    "target" device cannot be found.

    It's a trivial fix for one of the CONFIG_LEDS_CLASS ifdefs
