Two places used u32 where there should have been __le32.
Fixes sparse warnings:

However, note that checkpatch doesn't like your subject line.

Hm, I run checkpatch.pl from a pre-commit git hook, so it likely only
looks at the diff itself... I'll see if I can tweak the hook to check
a full patch generated from the commit.
It has a good point, though. I'll reword the subject.
