If anyone has any objections, please let me know. ------------------ From: Diogo Ivo [ Upstream commit f06777cf2bbc21dd8c71d6e3906934e56b4e18e4 ] Intel Over-Clocking Watchdogs are described in ACPI tables by both the generic PNP0C02 _CID and their ACPI _HID. The presence of the _CID then causes the PNP scan handler to attach to the watchdog, preventing the actual watchdog driver from binding. Address this by adding the ACPI _HIDs to the list of non-PNP devices, so that the PNP scan handler is bypassed. Note that these watchdogs can be described by multiple _HIDs for what seems to be identical hardware. This commit is not a complete list of all the possible watchdog ACPI _HIDs.
