hp-wmi: add rfkill support for wireless query 0x1b

2011-03-28T10:07:19Z

Some recent HP laptops use a new wireless query command type 0x1b. Add support for it. Tested on HP Mini 5102. Signed-off-by: Anssi Hannula Signed-off-by: Matthew Garrett

hp-wmi: make rfkill initialization failure non-fatal

2011-03-28T10:07:19Z

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

hp-wmi: clear rfkill device pointers when appropriate

2011-03-28T10:07:18Z

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.

hp-wmi: split rfkill initialization out of hp_wmi_bios_setup

2011-03-28T10:07:18Z

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: Anssi Hannula Signed-off-by: Matthew Garrett

hp-wmi: allow setting input and output buffer sizes separately

2011-03-28T10:07:18Z

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: Anssi Hannula Signed-off-by: Matthew Garrett

hp-wmi: remove a variable that is never read

2011-03-28T10:07:18Z

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: Anssi Hannula Signed-off-by: Matthew Garrett

hp-wmi: check query return value in hp_wmi_perform_query

2011-03-28T10:07:17Z

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: Anssi Hannula Signed-off-by: Matthew Garrett

ACPI, hp-wmi: Fix memory leak in acpi query

Input: hp-wmi - switch to using sparse keymap library

2010-10-21T13:36:43Z

Instead of implementing its own version of keymap hanlding switch over to using sparse keymap library. Also make sure that we install notify handler only after we allocated input device and that we remove notify handler before unregistering input device.

hp-wmi: Fix query interface

2010-08-23T20:27:08Z

The machines I have appear to provide their return value in the arguments structure, not the output structure. Rework the driver to use that again in order to get rfkill working again. Signed-off-by: Matthew Garrett
