  • Convert the backlight and LCD classes from struct class_device
    to struct device since class_device is scheduled for removal.

    One nasty API break is the backlight power attribute has had to be
    renamed to bl_power and the LCD power attribute has had to be renamed
    to lcd_power since the original names clash with the core. I can't see
    a way around this.

  • 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.

  • 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

  • Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
