No worries, welcome.

Starting with fixing a coding style defect or three is
just fine to learn how to compile and test the kernel.

But generally it's more useful to find things that make
the code better, more readable, smaller, faster, etc.

Also if you have some functional defect or enhancement
to implement, that's even better still.

Using an enum for a bool isn't very sensible.
true/false exist already.

I wouldn't bother with long line conversions unless
you're doing something else at the same time.

If you want to do them for the practice, please do
them on files in drivers/staging/.
