hp_wmi_rfkill_setup cleans up after itself now, so failing completely is no longer necessary. Signed-off-by:

NULLify rfkill pointers during initialization. This prevents dereference of invalid pointer in case the driver is rebound and some rfkill device isn't detected anymore. Clear them also in hp_wmi_rfkill_setup failure path so that an rfkill initialization failure doesn't need to be fatal for the whole driver. Signed-off-by:

Split initialization of rfkill devices from hp_wmi_bios_setup() to hp_wmi_rfkill_setup(). This makes the code somewhat cleaner, especially with the future command 0x1b rfkill support. Signed-off-by:

Split buffersize parameter of hp_wmi_perform_query to insize and outsize. Existing callers are changed to use the same value for insize and outsize to avoid any regressions, with the exception of hp_wmi_set_block where the output buffer is unused and therefore outsize is set to 0 (this change is not seen by BIOS code). The maximum input buffer size is kept at 4 bytes as per struct bios_args. Some commands exist that take longer buffers, but they haven't been implemented. The data portion of bios_args can be trivially made dynamically allocated later when such larger buffers become needed. Signed-off-by:

Remove the status variable from hp_wmi_perform_query which holds the return value from wmi_evaluate_method(). It is never checked as the function bails out if the output buffer hasn't been allocated which indicates the call failed. Signed-off-by:

Check BIOS provided return value code in hp_wmi_perform_query and print a warning on error. Printing is suppressed for HPWMI_RET_UNKNOWN_CMDTYPE which is returned when the command type is unsupported. Signed-off-by:

Reasonably recent Vaios have a 0x12f or 0x137 handler that exposes a fine lid backlight regulation with values ranging from 0 to 255. The patch is based on findings and code from Javier Achirica <achirica@gmail.com> and Marco Chiappero <marco@absence.it> Signed-off-by:

Recent Vaios have the opportunity to control the keyboard backlight via ACPI calls to the SNC device. Introduce two module parameters to control how keyboard backlight should be set at module loading (default to on and with 10 seconds timeout). Tested-by:

Avoid calling into acpi each time we need to lookup a method handle and report the available handles to ease collection of information when debugging issues. Also move initialization of the platform driver earlier to allow adding files from other setup functions. Signed-off-by:

There is not much use for these events in userspace and handling the events themselves seems to get in the way of the actual activation of the rf devices. The SNC device doesn't expose them already. https://bugzilla.kernel.org/show_bug.cgi?id=15303Signed-off-by:

Enable volume up and down hotkeys on WMI events GUID 284A0E6B-380E-472A-921F-E52786257FB4 and GUID 02314822-307C-4F66-bf0E-48AEAEB26CC8. Also works around a firmware bug where the _WED method should return an integer containing the key code and in fact the method returns the key code in element zero of a buffer.

These keys are supposed to be handled by any software using the camera (like webKam or cheese...). They can also be used to actually move the camera when possible. Signed-off-by:

I should have done that one year ago, so it's more than time to do it. These two features use non-standard interfaces. There are the only features that really need multiple path to guess what's the right method name on a specific laptop. Removing them allow to remove a lot of code an significantly clean the driver. This will affect the backlight code which won't be able to know if the backlight is on or off. The platform display file will also be write only (like the one in eeepc-laptop). Signed-off-by:

Asus took the DSDT from another model (L84F), made some change to make it work, but forgot to remove WLED method (the laptop doesn't have a wireless card). They even didn't change the model name. ref: https://bugzilla.kernel.org/show_bug.cgi?id=25712Signed-off-by:

I checked some more DSDT, and it seems that I wasn't totally right about the meaning of DSTS return value. Bit 0 is clearly the status of the device, and I discovered that bit 16 is set when the device is present. Signed-off-by:

\AMW0.WMBC, which is the main method that we use, is not reentrant. When wireless hotpluging is enabled, toggling the status of the wireless device using WMBC will trigger a notification and the notification handler need to call WMBC again to get the new status of the device, this will trigger the following error: ACPI Error (dswload-0802): [_T_0] Namespace lookup failure, AE_ALREADY_EXISTS ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20100428/psloop-231) ACPI Error (psparse-0537): Method parse/execution failed [\AMW0.WMBC] (Node f7023b88), AE_ALREADY_EXISTS ACPI: Marking method WMBC as Serialized because of AE_ALREADY_EXISTS error Since there is currently no way to tell the acpi subsystem to mark a method as serialized, we do it in eeepc-wmi. Of course, we could let the first call fail, and then it would work, but it doesn't seems really clean, and it will make the first WMBC call return a random value. This patch was tested on EeePc 1000H with a RaLink RT2860 wireless card using the rt2800pci driver. rt2860sta driver seems to deadlock when we remove the pci device... Signed-off-by:

Implement wireless like hotplug handling (code stolen from eeepc-laptop). Reminder: on some models rfkill is implemented by logically unplugging the wireless card from the PCI bus. Despite sending ACPI notifications, this does not appear to be implemented using standard ACPI hotplug - nor does the firmware provide the _OSC method required to support native PCIe hotplug. The only sensible choice appears to be to handle the hotplugging directly in the platform driver. Signed-off-by:
