Hans de Goede 3b6a70be5a ACPI / x86: Allow matching always_present_id array entries by DMI ... On some x86 systems the DSDT hides APCI devices to work around Windows driver bugs. On one such system the device is even hidden until a certain time after _SB.PCI0.GFX0.LCD.LCD1._ON gets called has passed *and* _STA has been called at least 3 times since. TL;DR: it is a mess. Until now the always_present_id matching was used to force status for a whole class of devices, e.g. always enable PWM1 on CHerry Trail devices. This commit extends the always_present_id matching code to optionally also check for a DMI match so that we can also add system specific quirks to the always_present_id array.
