I am sorry but I cannot take this patch as-is because it does way more
than what you claim. It makes a lot of cleanup changes which are totally
unrelated (yet welcome). Please create a series with:
- the fix (that can be backported) first, with Cc: stable and Fixes: tags
- all the cleanups you want to do after.

Thanks,
Miquèl
