Fails to compile on kernel 5.17 (Fedora 34)

[bc4040]

I have switched SUBDIRS= to M= as recommended in a previous issue, but now receive the following errors when compiling on 5.17 Fedora 34:

Were you able to resolve this issue? I'm running into the same error on Debian 11.

[bc4040]

No, but I was able to compile this forked version https://github.com/JamesRHarris/infinitv_pcie

That worked!!! Thanks for the quick reply, and thanks to @JamesRHarris for updating ctn91xx_event.c as well!!!
