Lorenz,

I do not see any attached material. Did you forget?

For the rest of readers: The GitHub repo containing the rtw88 drivers is 
essentially what is found at wireless-drivers-next with 2 exceptions: 1. 
Conditional compilation needed to account for kernel API changes is added, and 
2. I gnerally apply any patches sent by the Realtek authors as soon as they are 
posted in this ML. When there are fixes due to reviews, I update the sources.
