Applied to for-current, thanks! I added also this sentence from v2 to
the description to justify stable: "but causes -EINVAL to be returned
for valid transactions."

Also, this driver has no dedicated maintainer. Is there someone up for
this task? There is probably little to do and it will speed up patch
acceptance because I pick patches once the driver maintainer is happy.
