mainline build failure due to c8171a86b274 ("csky: Fixup -Wmissing-prototypes warning")

Hi All,

The latest mainline kernel branch fails to build csky allmodconfig with
the error:

git bisect pointed to c8171a86b274 ("csky: Fixup -Wmissing-prototypes warning").

Reverting the commit has fixed the build failure.

I will be happy to test any patch or provide any extra log if needed.

Thx for the report and involving regzbot. To make one thing more obvious:

Guo Ren, it seems to be caused by a commit of yours.

And fun fact: seem 0day bot found the same problem nearly thee weeks
ago, but nobody cared afaics:

Sorry, Fixes have been sent, I'm waiting for it into the linux-next,
and then I will send 2nd pull request.
