Working on a 6 month old kernel is not going to help at all, you need to
work on the latest tree at the least. linux-next is best. Otherwise
you end up making changes that can not be applied, or have already been
done by others, which is just a waste of time.

But what I asked is if you actually test built the change you made. As
the kbuild bot showed you, you obviously did not :(

Please always do that, you can not add new warnings to the kernel, nor
break the build with any change.

Also work on your knowledge of C before doing more kernel work, as the
change is not correct for the obvious reasons that it is not allowed by
the language. checkpatch is just a perl script, sometimes it give
incorrect information, like this time.

That does not match what your email "From:" says :)
