2008-10-22ACPI: Fix possible null ptr dereferencedonald.d.dugger@intel.com
Code in `pci_link.c' is calling the internal routine `acpi_ut_evaluate_object' which is dangerous given that it is passing a NULL pointer when it should be passing a pointer to a real object. The patch corrects the issue by having the code call the external routine `acpi_evaluate_object', which correctly handles a NULL pointer.

2008-10-22ACPI : Load device driver according to the status of acpi deviceZhao Yakui
According to ACPI spec when the status of some device is not present but functional, the device is valid and the children of this device should be enumerated. It means that the device should be added to linux acpi device tree. But the device driver for this device should not be loaded. The detailed info can be found in the section 6.3.7 of ACPI 3.0b spec. _STA may return bit 0 clear (not present) with bit 3 set (device is functional). This case is used to indicate a valid device for which no device driver should be loaded (for example, a bridge device.). Children of this device may be present and valid. OS should continue enumeration below a device whose _STA returns this bit combination http://bugzilla.kernel.org/show_bug.cgi?id=3358 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Li Shaohua <shaohua.li@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

transition Maybe the incorrect power state is returned on the bogus bios, which is different with the real power state. For example: the bios returns D0 state and the real power state is D3. OS expects to set the device to D0 state. In such case if OS uses the power state returned by the BIOS and checks the device power state very strictly in power transition, the device can't be transited to the correct power state. So the boot option of "acpi.power_nocheck=1" is added to avoid checking the device power in the course of device power transition. http://bugzilla.kernel.org/show_bug.cgi?id=8049 http://bugzilla.kernel.org/show_bug.cgi?id=11000 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Li Shaohua <shaohua.li@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2008-10-22ACPI: Get the device power state in the course of scanning deviceZhao Yakui
Get the device power state in the course of scanning device if the device power flag is power_managable. i.e. The device has the _PSx/_PRx object. At the same time before the drivers/acpi/power module is loaded, there is no relation between acpi_power_resource and acpi device. So the first parameter of acpi_power_get_state is changed to acpi_handle. http://bugzilla.kernel.org/show_bug.cgi?id=8049 http://bugzilla.kernel.org/show_bug.cgi?id=11000 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Li Shaohua <shaohua.li@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2008-10-22ACPI: replace AE_BAD_ADDRESS exception code with AE_ERRORLin Ming
The AE_BAD_ADDRESS exception code is now unused in ACPICA. For linux, it's only used at wmi.c and acer-wmi.c. I checked both wmi.c and acer-wmi.c, the AE_BAD_ADDRESS exception code has no special meaning. The parent functions just call AE_SUCCESS() or AE_FAILURE() to check the return status. So it's safe to replace AE_BAD_ADDRESS with AE_ERROR. Signed-off-by Lin Ming <ming.m.lin@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2008-10-08acer-wmi: Add rfkill support for wireless and bluetoothCarlos Corbacho
This patch implements rfkill support for the wireless and bluetooth devices commonly found on Acer laptops. For now, we will always poll these devices once a second to guarantee we can catch state changes. On newer Acer laptops, it may be possible to rely on WMI events to do this instead, and experimental support for this will be added in a later patch. 3G has been deliberately left off for now, as we still have no way to detect it, (nor, AFAIK, has any Linux user tried the code) and on laptops that don't support 3G, trying to poll for the status will leave the logs full of ACPI tracebacks. The old sysfs interface for wireless and bluetooth will be removed in a later patch. (Thanks to Henrique de Moraes Holschuh and Dmitry Torokhov for reviewing this patch).

2008-10-06atmel-mci: Initialize BLKR before sending data transfer commandHaavard Skinnemoen
The atmel-mci driver sometimes fails data transfers like this: mmcblk0: error -5 transferring data end_request: I/O error, dev mmcblk0, sector 2749769 end_request: I/O error, dev mmcblk0, sector 2749777 It turns out that this might be caused by the BLKR register (which contains the block size and the number of blocks being transfered) being initialized too late. This patch moves the initialization of BLKR so that it contains the correct value before the block transfer command is sent. This error is difficult to reproduce, but if you insert a long delay (mdelay(10) or thereabouts) between the calls to atmci_start_command() and atmci_submit_data(), all transfers seem to fail without this patch, while I haven't seen any failures with this patch.

2008-10-04V4L/DVB (8958): zr36067: Return proper bytes-per-line valueJean Delvare
The zr36067 driver should return the actual bytes-per-line value when queried with ioctl VIDIOC_G_FMT, instead of 0. Otherwise user-space applications can get confused. Likewise, with ioctl VIDIOC_S_FMT, we are supposed to fill the bytes-per-line value. And we shouldn't fail if the caller sets the initial value to something different from 0. This is perfectly valid for applications to pre-fill this field with the value they expect. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-10-04V4L/DVB (8957): zr36067: Restore the default pixel formatJean Delvare
Restore the default pixel format to YUYV as it used to be before kernel 2.6.23. It was accidentally changed to BGR3 by commit 603d6f2c8f9f3604f9c6c1f8903efc2df30a000f. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-10-04V4L/DVB (8955): bttv: Prevent NULL pointer dereference in radio_openJean Delvare
Fix the following crash in the bttv driver: BUG: unable to handle kernel NULL pointer dereference at 000000000000036c IP: [<ffffffffa037860a>] radio_open+0x3a/0x170 [bttv] This happens because radio_open assumes that all present bttv devices have a radio function. If a bttv device without radio and one with radio are installed on the same system, and the one without radio is registered first, then radio_open checks for the radio device number of a bttv device that has no radio function, and this breaks. All we have to do to fix it is to skip bttv devices without a radio function. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
