You always have to build-test your changes, as you have found out.

There is nothing wrong with the original code here. Remember that
checkpatch is a perl script that gives good advice, but it is not always
correct. You must always manually check it based on your knowledge of
the C language.
I recommend learning a bit more C before working on kernel code.
Best of luck!
