Fixing trivial warnings

[Nelson Castillo]

Let's fix simple warnings first.

PS: I need a git-send-email hint. How do you use it?

I used it like this and the subject doesn't change.

    git-send-email -no-chain-reply-to \
     --compose --suppress-from \
    --smtp-server /usr/bin/msmtp \
    --to "openmoko-kernel at lists.openmoko.org" \
    --cc "" 00*.patch
