I found a USB WLAN Stick with a rtl8192u. I got it last Saturday and 
found out that the firmware is missing in my ubuntu 20.04. I found it on 
the web and fixed it. When I started the driver my computer crashed. The 
missing part was: priv->priv_wq = alloc_workqueue("priv_wq", 0, 0); 
Fixing this the next error was a network = kzalloc(sizeof(*network), 
GFP_KERNEL); in wrong context with leads to a crash of my computer. 
Fixing this leads to another issue which lets my computer crash.

For me the firmware of rtl8192u was intentionally missing because of the 
issues with the driver.

What this has to do with your question?
Can we check for missing firmware in main distributions to know which 
drivers are considered to be old and unused?
