[PATCH v2 1/3] ACPI / EC: Enhance boot EC sanity check

2017-05-19 Thread Lv Zheng
It's reported that some buggy BIOS tables can contain 2 DSDT ECs and one of them is invalid. As we shouldn't evaluate _STA from acpi_ec_dsdt_probe() due to the unknown Windows enumeration order, this patch simply enhances sanity checks in ec_parse_device() as a workaround to skip probing wrong
