Bug#985956: #985956 - missing kernel module in installer

[Pete Batard]

For reference I have submitted a new pull request against src:linux that 
attempts to fix this in 
https://salsa.debian.org/kernel-team/linux/-/merge_requests/350

As people who monitor the Debian ARM64 mailing list should be aware, 
this is a rather major issue, that people wanting to install Debian on 
the Raspberry Pi 4 are running into, and that we have eagerly been 
waiting to see fixed, even more so as the Bullseye release is fast 
approaching...
