backlight: Add support for MacBook 5, MacBook Air 2, and MacBook Pro 5
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.

leds: move h1940-leds's probe function to .devinit.text
A pointer to h1940leds_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.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

leds: add BD2802GU LED driver
ROHM BD2802GU is a RGB LED controller attached to i2c bus and specifically
engineered for decoration purposes. This RGB controller incorporates
lighting patterns and illuminates.
This driver is designed to minimize power consumption, so when there is no
emitting LED, it enters to reset state. And because the BD2802GU has lots
of features that can't be covered by the current LED framework, it
provides Advanced Configuration Function(ADF) mode, so that user
applications can set registers of BD2802GU directly.
Here are basic usage examples :
; to turn on LED (not blink)
$ echo 1 > /sys/class/leds/led1_R/brightness
; to blink LED
$ echo timer > /sys/class/leds/led1_R/trigger
$ echo 1 > /sys/class/leds/led1_R/delay_on
$ echo 1 > /sys/class/leds/led1_R/delay_off
; to turn off LED

It's useful for usecases as n810's keypad leds that could

up to show the keypad.
We also provide means for userland to tell us what is the

The existing probe and remove methods are refactored to use new functions
create_gpio_led(), to create and register one led, and delete_gpio_led(),
to unregister and free one led. The new probe and remove methods for the
of_platform driver can then share most of the common probe and remove code
with the platform driver.
The suspend and resume methods aren't shared, but they are very short. The

audit record emitted may then contain a NULL and then whatever random memory
is after the NULL.
Since we want to log the entire octet stream (if we can't trust the data
to be a string we can't trust that a NULL isn't actually a part of it)
we should just consider NULL as a control character. If the caller is
certain they want to stop at the first NULL they should be using
audit_log_untrustedstring.

audit: EXECVE record - removed bogus newline
(updated)
Added hunk that changes the comment, the rest is the same.
EXECVE records contain a newline after every argument. auditd converts
"\n" to " " so you cannot see newlines even in raw logs, but they're
there nevertheless. If you're not using auditd, you need to work round
them. These '\n' chars are can be easily replaced by spaces when
creating record in kernel. Note there is no need for trailing '\n' in
an audit record.

ACPI: support acpi_device_ops .notify methods
This patch adds support for ACPI device driver .notify() methods. If
such a method is present, Linux/ACPI installs a handler for device
notifications (but not for system notifications such as Bus Check,
Device Check, etc). When a device notification occurs, Linux/ACPI
passes it on to the driver's .notify() method.
In most cases, this removes the need for drivers to install their own
handlers for device-specific notifications.
For fixed hardware devices like some power and sleep buttons, there's
no notification value because there's no control method to execute a
Notify opcode. When a fixed hardware device generates an event, we
handle it the same as a regular device notification, except we send
a ACPI_FIXED_HARDWARE_EVENT value. This is outside the normal 0x0-0xff
range used by Notify opcodes.
Several drivers install their own handlers for system Bus Check and
Device Check notifications so they can support hot-plug. This patch
doesn't affect that usage.
