There are various bits of code here that are unfinished and instead of
being harmless either confuse or spew stuff into the logs at higher than
debug level. They can and should go away.
Also remove the bogus use of tty->lowlatency. We fixed the need for this hack
long ago (with the flip buffer rewrite) but people keep copying it into drivers.

mxser_check_modem_status is called with tty parameter, so the
reference should be increased by callers already -- for ioctl
syscall it is held whole time gap since open to close, for
interrupt, the reference count is increased in the irq handler.
There is no tty_kref_put in that function, so this also fixes
a refcounting bug.

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.

Sometimes it's awkward to make sure that the array in the
platform_data handed to the leds-gpio driver has only valid
data ... some leds may not be always available, and coping
with that currently requires patching or rebuilding the array.
This patch fixes that by making it be OK to pass an invalid
GPIO (such as "-EINVAL") ... such table entries are skipped.

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.

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
$ echo 0 > /sys/class/leds/led1_R/brightness
