Make sure to drop the reference taken by bus_find_device_by_name()
before returning from mfd_clone_cell().
Fixes: a9bbba996302 ("mfd: add platform_device sharing support for mfd")

I do not see this one in linux-next (or your tree). Did you forget to
push?

Since I tend to flit between maintaining and real-work, I tend to bulk
push once I have a bunch of fixes/updates. Your fix should appear in
-next tomorrow. The plan is to have it in upstream by next week.
