For linux driver development you can start by reading "Linux Device Drivers, Third Edition" pdf.
It is free and give you an idea about how everything works.
The real learning is by reading and using the linux kernel api doc or directly the source code of the api you want to call.
Source : i did this for a school project where i had to implement multiple kernel modules.
I think the real issue with driver development is that almost nobody ever has a reason to do it. It's a much more constrained way of programming compared to normal programs, and isn't necessary unless you need to talk to hardware or something. So, nobody has an excuse to learn it.
“There are lots of books on harvesting your own primal power source, but most people these days make a pact with the demon Linus and simply channel his power”
This makes me feel so much better after spending a morning banging my head against some wild pointer arithmetic, thank you much much! (Ultimately the pointer incantations were successful, praise be!)
