Add device HID AMDI0031 to the AMD GPIO controller driver match table. This controller can be found on Microsoft Surface Laptop 4 devices and seems similar enough that we can just copy the existing AMDI0030 entry.

Why? It's hardly a regression?
Because that ID is already in use on the Surface Laptop 4 and potentially other AMD-based laptops that are already available for purchase. Not having it in stable means that people may have to deal with some things not working (as this may prevent other drivers relying on GPIOs from working) until 5.14 is available on their distribution of choice.
Given the size of this change, I hardly think that's necessary. Which is, I believe, also why the stable-kernel-rules doc points out that new device IDs are (generally) allowed.
