Driver does not work with Linux 5.19.2

[Spixmaster]

There are several compilation issues. Besides that, I tried the built in driver in the Linux kernel which still does not work. The connection is not established.

If someone is feeling adventurous they could try the patch from https://github.com/loqs/rtl8821ce-dkms-git/blob/master/rtl8821ce-5.19.2.patch which is build tested only based on a request in https://bbs.archlinux.org/viewtopic.php?id=278991

Don't you want to create a pull request?

[loqs]

Not as it is untested.

I am adventurous and it did indeed install and work for me with linux-amd-raven 5.19.2
