If you are referring to my recent patchset it was about platform and
i2c drivers where appropriate register functions do it (e.g.
i2c_register_driver()). But regulator_register passes owner from
regulator_desc:
rdev->owner = regulator_desc->owner;
and then calls device_register(). I think the owner for regulator
device won't be set.

Best regards,
Krzysztof
