platform/x86: asus-wmi: try to set als by default
some laptops, for example ASUS UX330UAK, have brocken als_get function but working als_set funktion. In this case, ALS will stay turned off. Method (WMNB, 3, Serialized) { ... If (Local0 == 0x53545344) { ... If (IIA0 == 0x00050001) { If (!ALSP) { Return (0x02) } Local0 = (GALS & 0x10) <<<---- bug, should be: (GALS () & 0x10) If (Local0) { Return (0x00050001) } Else { Return (0x00050000) } } ..... If (Local0 == 0x53564544) { ... If (IIA0 == 0x00050001) { Return (ALSC (IIA1)) } ...... Method (GALS, 0, NotSerialized) { Local0 = Zero Local0 |= 0x20 If (ALAE) { Local0 |= 0x10 } Local1 = 0x0A Local1 <<= 0x08 Local0 |= Local1 Return (Local0) } Since it works without problems on Windows I assume ASUS WMI driver for Win never trying to get ALS state, and instead it is setting it by default to ON. This patch will do the same. Turn ALS on by default. Signed-off-by: Oleksij Rempel <linux@rempel-privat.de> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
