acer-wmi: Add driver for newer Acer laptops (745a5d21) · Commits · 戴 / test

This is a driver for newer Acer (and Wistron) laptops. It adds wireless radio and bluetooth control, and on some laptops, exposes the mail LED and LCD backlight. v1: * Initial release v2: * Replace left over ACPI references with WMI * Add GUID based autoloading (depends on future work to WMI) * Add DMI based autoloading (backup solution until WMI sysfs/ class work is available) * Checkpatch fixes v3: * Add new EC quirks for Aspire 3100 & 5100, and Extensa 5220 v4: * Simplified internal handling of WMID and AMW0 devices * Add autodetection for bluetooth and maximum brightness on AMW0 V2 and WMID laptops. v5: * Add EC quirk for Medion MD 98000 * Add autodetection for AMW0, and mail LED on AMW0 and AMW0 V2. * Improve error handling * Fix AMW0 V2 bluetooth and wireless, by using both WMID and AMW0 methods to ensure that the correct value is always set. v6: * Fix 'use before initialisation' bug with quirks. v7 * Fix bug on AMW0 where acer-wmi would exit if a mail LED was not detected. * Add Acer Aspire 9110 mail LED support * Fix section mismatch warnings Signed-off-by:
