I started rebasing and realised that your approach has swapped the error codes,
i.e. if it's a single-value and it is, e.g., 16-bit wide, the u8 read will
return 1, while it has to return -EOVERFLOW.
If you prefer, I can move two patches to the beginning, so one will be a good
prerequisite for this fix. And I'm still unsure about stable (Fixes tag is okay
to me), because the counting never worked from the day 1.
