I tend to use W=1 before submitting a patch since not everything is
being caught by ./scripts/checkpatch.pl. So this trivial patch was
simply a way for me to remove some warning pollution I was seeing on
my branch (not clear why this specific warning is considered an error
in other section of the linux tree). This is a custom pmac32 branch,
gcc version is:

$ powerpc-linux-gnu-gcc --version
powerpc-linux-gnu-gcc (Debian 6.3.0-18) 6.3.0 20170516

Feel free to drop it if this is too much noise.

Thanks
