In ath10k and ath11k I have tried to avoid that and instead declare all
variables in the beginning of the function, this is to keep the code
simple. Of course there are few cases where a variable is declared in
the middle of the function, but that's just sloppy review on my part. I
feel that it's better to refactor the function into smaller functions
than start declaring variables in the middle of functions. Does that
make sense?
