This patch removes the keyword from the definition part, while keeps
it in
the declaration part.

I think checkpatch also says that extern should be avoided in declarations.

Thanks for the review. I tried to look at this complain, but I didn't see
this behavior on checkpatch.pl from kernel 4.19. I created a commit that adds
a new extern prototype and checked the patch. Take a look:

Use option --strict with checkpatch.pl
