.. probably. But we have a ton of other uses that just pass in
"result" pointers (not structs), which admittedly don't have the
padding issue, but do have the exact same issue otherwise.

We have those random "initialize to zero by hand", and I wouldn't
actually worry about most of the common cases. KASAN will find them
anyway.

It tends to be the random odd ioctl-like things that nobody finds
because it's only uninitialized for some silly error case that never
triggers (or some unusual driver that needs to be loaded).
