2012-03-26drivers/platform/x86/amilo-rfkill.c::amilo_rfkill_probe() avoid NULL derefJesper Juhl
In drivers/platform/x86/amilo-rfkill.c::amilo_rfkill_probe() the call to dmi_first_match() may fail and return NULL. If it does return NULL, then we'll be dereferencing a NULL pointer in the rfkill_alloc() call where we do 'system_id->driver_data' --> KABOOM! Avoid that problem by testing for a NULL return value from dmi_first_match() and bailing out if it fails. I was a bit uncertain about what to return in the failure case. In the end I settled for -ENXIO as the most logical error to return. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2012-03-26samsung-laptop: unregister ACPI video module for some well known laptopsCorentin Chary
On these laptops, the ACPI video is not functional, and very unlikely to be fixed by the vendor. Note that intel_backlight works for some of these laptops, and the backlight from samsung-laptop always work. The good news is that newer laptops have functional ACPI video device and won't end up growing this list.

2012-03-26asus-wmi: store backlight power status for AIO machineAceLan Kao
Due to some implementation reasons, ASUS ET2012 All-in-One machines can't report the correct backlight power status, it will always return 1. To track the backlight power status correctly, we have to store the status by ourselves. BTW, by the BIOS design, the backlight power will be turn on/off sequently, no matter what the value of the parameter will be. More over, the brightness adjustment command will turn on the backlight power. Those behaviors will make us fail to track the backlight power status. For example, While we are trying to turn on the backlight power, we will send out the brightness adjustment command and then trying to figure out if we have to turn on the backlight power, then send out the command. But, the real case is that, the backlight power turns on while sending the brightness adjustment command, and then we send out the command to turn on the backlight power, it actually will turn off the backlight power and the backlight power status we recorded becomes wrong. So, we have to seperate these two commands by a if statement.

2012-03-26asus-wmi: add scalar board brightness adj. supportAceLan Kao
Some ASUS ET2012E/I All-in-One machines that use a scalar board to control the brightness, and they only accept brightness up and down command. So, I introduced a get_scalar_command() function to pass the command to the scalar board through WMI. Besides, we have to store the brightness value locally, for we need the old value to know the brightness value is increasing or decreasing. BTW, since there is no way to retrieve the actual brightness(it would be a fixed value), and the max brightness value would be fixed to 1, so we have to keep passing the brightness up/down command when we reached the max brightness value or 0.

2012-03-26perf tools: Fix bug in raw sample parsingStephane Eranian
In perf_event__parse_sample(), the array variable was not incremented by the amount of data used by the raw_data. That was okay until we added PERF_SAMPLE_BRANCH_STACK which depends on the array variable pointing to the beginning of the branch stack data. But that was not the case if branch stack was combined with raw mode sampling. That led to bogus branch stack addresses and count. The bug would show up with: $ perf record -R -b foo This patch fixes the problem by correctly moving the array pointer forward for RAW samples.

2012-03-26ab8500-charger: AB8500 charger driverArun Murthy
This driver is responsible for detecting the ac/usb plugin and also includes function to enable ac/usb charging and re-kick the watchdog. It registers with the power supply class and provides information to the user space. The information include status of ac/usb charger device. This information in turn will be used by the abx500 charging algorithm driver to enable/disable and monitor charging.

2012-03-26abx500-chargalg: Add abx500 charging algorithmArun Murthy
This is a charging algorithm driver for abx500 variants. It is the central entity for battery driver and is responsible for charging and monitoring the battery driver. It is a hardware independant driver and also monitors other abx500 power supply devices.
