sgi-gru: call fs_initcall() if statically linked

2008-12-02T23:51:35Z

If xpc.ko and gru.ko are both statically linked into the kernel, then xpc_init() can get called before gru_init() and make a call to one of the gru's exported functions before the gru has initialized itself. The end result is a NULL dereference. Signed-off-by: Dean Nelson Signed-off-by: Linus Torvalds

ACPI: thinkpad-acpi: fix fan sleep/resume path

2008-11-27T00:24:22Z

This fixes a regression from v2.6.27, caused by commit 5814f737e1cd2cfa2893badd62189acae3e1e1fd, "ACPI: thinkpad-acpi: attempt to preserve fan state on resume". It is possible for fan_suspend() to fail to properly initialize fan_control_desired_level as required by fan_resume(), resulting on the fan always being set to level 7 on resume if the user didn't touch the fan controller. In order to get fan sleep/resume handling to work right: 1. Fix the fan_suspend handling of the T43 firmware quirk. If it is still undefined, we didn't touch the fan yet and that means we have no business doing it on resume. 2. Store the fan level on its own variable to avoid any possible issues with hijacking fan_control_desired_level (which isn't supposed to have anything other than 0-7 in it, anyway). 3. Change the fan_resume code to me more straightforward to understand (although we DO optimize the boolean logic there, otherwise it looks disgusting). 4. Add comments to help understand what the code is supposed to be doing. 5. Change fan_set_level to be less strict about how auto and full-speed modes are requested. http://bugzilla.kernel.org/show_bug.cgi?id=11982 Signed-off-by: Henrique de Moraes Holschuh Reported-by: Tino Keitel Signed-off-by: Len Brown

sony-laptop: brightness regression fix

2008-11-26T23:12:07Z

After commit 540b8bb9c33935183ceb5bed466a42ad72b2af56: sony-laptop: fingers off backlight if video.ko is serving this functionality I can't set brightness on my sony laptop (nothing in /sys/class/backlight). dmesg says "sony-laptop: Sony: Brightness ignored, must be controlled by ACPI video driver". The function acpi_video_backlight_support returns 0 if we should use the vendor-specific backlight support, while non-0 if the ACPI generic should be used. Because of this, the check introduced by the said commit appears reversed. Signed-off-by: Alessandro Guido Signed-off-by: Len Brown

Add c2 port support

2008-11-13T01:17:18Z

C2port implements a two wire serial communication protocol (bit banging) designed to enable in-system programming, debugging, and boundary-scan testing on low pin-count Silicon Labs devices. Currently this code supports only flash programming through sysfs interface but extensions shoud be easy to add.
