Missing braces here.

And here too.

Generally the rule with QEMU is that as you change parts of the code 
that haven't been touched for a while, you should update them to meet 
the new style guidelines. Did you run the diffs through 
scripts/checkpatch.pl at all as that should catch styling points like this?
