In the Linux kernel, the following vulnerability has been resolved:

LoongArch: Fix potential ADE in loongson_gpu_fixup_dma_hang()

The switch case in loongson_gpu_fixup_dma_hang() may not DC2 or DC3, and readl(crtc_reg) will access with random address, because the "device" is from "base+PCI_DEVICE_ID", "base" is from "pdev->devfn+1". This is wrong when my platform inserts a discrete GPU:

lspci -tv -[0000:00]-+-00.0 Loongson Technology LLC Hyper Transport Bridge Controller ... +-06.0 Loongson Technology LLC LG100 GPU +-06.2 Loongson Technology LLC Device 7a37 ...

Add a default switch case to fix the panic as below:
