In the earlier check we assumed that "obj" could be NULL. I looked at some of the other places that call evaluate_object() and they check for NULL as well. Signed-off-by:

dmi_check_system() walks the table running matching functions until someone returns non zero or we hit the end. This patch makes dmi_check_cb to return 1 so dmi_check_system() return immediately when a match is found. Signed-off-by:

I found the commit 80183a4b "compal-laptop/fujitsu-laptop/msi-laptop: make dmi_check_cb to return 1 instead of 0" has wrong patch merge. The original patch change the return value for dmi_check_cb(): https://lkml.org/lkml/2010/7/2/88 But commit 80183a4b changed the return value for set_backlight_level. Signed-off-by:

MSI BIOS's raw behavior is send out KEY_TOUCHPAD_TOGGLE key when user pressed touchpad hotkey. Actually, we can capture the real touchpad status by read 0xE4 EC address on MSI netbook/notebook. So, add msi-laptop input device for send out KEY_TOUCHPAD_ON or KEY_TOUCHPAD_OFF key when user pressed Fn+F3 touchpad hotkey. It leave userland applications to know the real touchpad status. Tested on MSI netbook U-100, U-115, U160(N051), U160DX, N014, N034 Tested on MSI notebook CR620 Cc: Carlos Corbacho <carlos@strangeworlds.co.uk> Cc: Matthew Garrett <mjg@redhat.com> Cc: Dmitry Torokhov <dtor@mail.ru> Cc: Corentin Chary <corentincj@iksaif.net> Signed-off-by:

Introduce a new driver for Asus Notebooks shipped with a WMI device instead of the old ACPI device. The WMI device is almost the same as the one present in Eee PC, but the event guid and the keymap are different. The keymap comes from asus-laptop module. On Asus notebooks, when you call the WMI device, you always need a 64bit buffer, even if you only want to get the state of a device (tested on a G73). Signed-off-by:

This is tricky, new WMI aware notebooks seems to use 0x53545344 while Eee PCs are using 0x53544344. But there is no way to know if there is an Eee PC in that wild that is using 0x53545344 or a notebook using 0x53544344. So the driver try to guess the available DSTS method ... But most Eee PCs never return 0xFFFFFFFE when a method is not available, they return 0 instead (and that's useless). So, first, try 0x53544344 then 0x53545344. We will find a better way when we got more data. Signed-off-by:

This patch create a single function to call the WMI methods. This function handle inexistent methods (when implemented by the WMI devices, and this is not the case on Eee PCs), ACPI errors, etc.. Also pack struct bios_arg, and make sure that we always send a 64bit buffer when calling a WMI method, because this is needed on Asus notebooks. Signed-off-by:

New Asus notebooks are using a WMI device similar to the one used in Eee PCs. Since we don't want to load eeepc-wmi module on Asus notebooks, and we want to keep the eeepc-wmi module for backward compatibility, this patch introduce a new module, named asus-wmi, that will be used by eeepc-wmi and the new Asus Notebook WMI Driver. eeepc-wmi's input device strings (device name and phys) are kept, but rfkill and led names are changed (s/eeepc/asus/). This should not break anything since rfkill are used by type or index, not by name, and the eeepc::touchpad led wasn't working correctly before 2.6.39 anyway. 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 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:
