Around line 796, there's irq_to_desc which shouldn't be used in a module. afaik, it's for kernel use only.
See https://patchwork.kernel.org/project/linux-rdma/patch/[email protected]/
Kernel 5.10 and on won't export irq_to_desc any longer. As mentioned, it is to stop the abuse of it.
From now on this usage will only result in an undefined error:
ERROR: modpost: "irq_to_desc" [/home/sysghost/Sources/spi-ch341-usb/spi-ch341-usb.ko] undefined!
