Hi-
I've seen the following panic on shutdown for about
a week. I've been fighting a stomach bug, so I
haven't been able to drill into it until now. I'm
bisecting, but thought I should report the issue
now.

driver core: platform: use bus_type functions
[ Upstream commit 9c30921fe7994907e0b3e0637b2c8c0fc4b5171f ]
This works towards the goal mentioned in 2006 in commit 594c8281f905
("[PATCH] Add bus_type probe, remove, shutdown methods.").
The functions are moved to where the other bus_type functions are
defined and renamed to match the already established naming scheme.

which even seems plausible.
Ugh... It was a larger backport on 5.10, I'll drop all of that. Thats
for looking into it!
