This appears to leak references to the struct devices returned by
class_find_device() - it takes a reference before it returns so any
device found using class_find_device() needs to be released with
put_device() and I don't see any new put_device() calls in here.

This is not the case at all, this patch was newly added.  If you want
to include changelogs like this in the patch description try to ensure
that they bear some relationship to reality, if they don't they are
actively harmful as they are likely to mislead or annoy the reader.
