2010-10-21ideapad: Change the driver name to ideapad-laptopIke Panhc
Since the platform drivers doing more for laptops than just using specific ACPI device. It will be good to change the name from *_acpi to *-laptop.

2010-10-21WMI: embed struct device directly into wmi_blockDmitry Torokhov
Instead of creating wmi_blocks and then register corresponding devices on a separate pass do it all in one shot, since lifetime rules for both objects are the same. This also takes care of leaking devices when device_create fails for one of them. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Matthew Garrett <mjg@redhat.com>

2010-10-21toshiba-acpi - switch to using sparse keymapDmitry Torokhov
Instead of implementing its own version of keymap hanlding switch over to using sparse keymap library. Also, install notify handler only after we allocated input device, otherwise we may risk getting event too early and crash.

2010-10-05[PATCH 2/2] IPS driver: disable CPU turboJesse Barnes
The undocumented interface we're using for reading CPU power seems to be overreporting power. Until we figure out how to correct it, disable CPU turbo and power reporting to be safe. This will keep the CPU within default limits and still allow us to increase GPU frequency as needed.

2010-10-05IPS driver: apply BIOS provided CPU limit if different from defaultJesse Barnes

2010-10-05intel_ips -- ensure we do not enable gpu turbo mode without driver linkageAndy Whitcroft
Both when polling the current turbo status (in poll_turbo_status mode) and when handling thermal events (in ips_irq_handler) the current status of GPU turbo is updated to match the hardware status. However if during driver initialisation we were unable aquire linkage to the i915 driver enabling GPU turbo will lead to an oops on the first attempt to determine GPU busy status. Ensure that we do not enable GPU turbo unless we have driver linkage.

2010-10-05NULL pointer might be used in ips_monitor()minskey guo
The patch is to create ips_adjust thread before ips_monitor begins to run because the latter will kthread_stop() or wake up the former via ips->adjust pointer. Without this change, it is possible that ips->adjust is NULL when kthread_stop() or wake_up_process() is called in ips_monitor().

2010-08-23ACPI_TOSHIBA needs LEDS supportJonathan Corbet
Don't ask how ACPI_TOSHIBA got enabled on in desktop system's .config - I don't know. But it has silently been there until I tried 2.6.36-rc2, where it broke the build because I don't have LED support turned on. Attached patch fixes things up. (I had to change BACKLIGHT_CLASS_DEVICE to "depends" because otherwise I get unsightly core dumps out of scripts/kconfig/conf). jon -- toshiba: make sure we pull in LED support The Toshiba extras driver uses the LED module, so make sure we have it configure in.
