This patchset replaces the HWMON asus_wmi_ec_sensors driver with an implementation that does not use WMI but queries the embedded controller directly. That provides two enhancements: sensor reading became quicker (on some systems or kernel configuration it took almost a full second to read all the sensors, that transfers less than 15 bytes of data), the driver became more fexible. The driver now relies on ACPI mutex to lock access to the EC, in the same way as the WMI DSDT code does. Changes in v2: - Replace sensor flags enum with bitset - Replace module init/probe functions with module_platform_driver_probe and ask the platform drivers framework to load the driver when ACPI EC is found (ACPI ID "PNP0C09"). - Extend board data with BIOS version attribute for the mutex path to be BIOS version dependent. - Add module parameter to override the mutex path.
