* Some ACPI devices are hidden (status == 0x0) in recent BIOS-es because |

|
* |
|
* Some BIOS-es (temporarily) hide specific APCI devices to work around Windows |
|
* driver bugs. We use DMI matching to match known cases of this. |
|
* |
|
* Likewise sometimes some not-actually present devices are sometimes |
|
* reported as present, which may cause issues. |
|
* |
|
* We work around this by using the below quirk list to override the status |
|
* reported by the _STA method with a fixed value (ACPI_STA_DEFAULT or 0). |
|
* Note this MUST only be done for devices where this is safe. |
|
* |
|
* This status overriding is limited to specific CPU (SoC) models both to |
|
* avoid potentially causing trouble on other models and because some HIDs |
|
* are re-used on different SoCs for completely different devices. |
