update the define used in this driver accordingly. The structs were also
renamed to fix a spelling typo.

Certain hardware will send us events when the backlight brightness
changes. Add a function to update the value in the core, and
additionally send a uevent so that userspace can pop up appropriate
UI. The uevents are flagged depending on whether the update originated
in the kernel or from userspace, making it easier to only display UI
at the appropriate time.

A pointer to hp680bl_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

The WM831x series of PMICs provide DC-DC boost convertors and current
sinks which can be used together to drive LEDs for use as backlights.
Expose this functionality via the backlight API.
Since when used in this configuration the current sink and boost
convertor are very tightly coupled with a multi-stage startup for
the current sink which overlaps with the boost convertor startup
this driver bypasses the regulator API. Machine inititialisation
is responsible for ensuring that the regulators are not accessed
via both APIs.

When suspending, pwm-bl sets duty cycle to 0, and shuts down the pwm
device.
This patch ensure that the platform code is called before that
(through the notify callback_, leaving a chance for the platform code
to configure GPIOs (shutting off the backlight, for example), much like
it is done during normal operations.

fb_notifier_call_chain() is called with info->lock held, i.e. in
do_fb_ioctl() => FBIOPUT_VSCREENINFO => fb_set_var() and the some
notifier callbacks, like fbcon_event_notify(), try to re-acquire
info->lock again.
Remove the lock/unlock_fb_info() in all the framebuffer notifier
callbacks' and be sure to always call fb_notifier_call_chain() with
info->lock held.

This patch adds support for the new Apple models incorporating an Nvidia
chipset. Apple still uses the same protocol as on older models, but the
registers moved to a different address. To do this, two sets of functions
are added for the Intel/Nvidia chipset models and passed by the DMI_MATCH
function.
The initial code has been contributed by Hu Gang <hugang@soulinfo.com>.
The driver is known to work on MacBook Pro 3, MacBook Pro 4 and MacBook
Pro 5.
Its known to work with limitations on MacBook 5 / MacBook Air 2. Changing
brightness within X doesn't work, if using Nvidia's proprietary graphics
driver with no known fix at present. Changing brightness on a text console
or using the open-source driver does work.
MacBook Pro 5 has a known bug where the initial brightness after bootup is
the last recently used brightness (in Mac OSX), while the firmware reports
maximum. Impossible to fix.

Fix a circular locking dependency in the frame buffer console driver
pushing down the mutex fb_info->lock.
Circular locking dependecies occur calling the blocking
fb_notifier_call_chain() with fb_info->lock held. Notifier callbacks can
try to acquire mm->mmap_sem, while fb_mmap() acquires the locks in the
reverse order mm->mmap_sem => fb_info->lock.
