I think Pat named it and I always think of it as "device vs. driver".c
as it handles all of the device and driver interactions between binding
and unbinding and other fun logic there.  I'm all for a new name if
anyone has any ideas, "probe.c" is sane, but it also handles disconnect
logic.  "core.c" already has lots of device functions, so renaming it to
"device.c" would be confusing.  I don't know...

Yeah, in digging, Pat did this in commit 07e4a3e27fe4 ("[PATCH] Move
device/driver code to drivers/base/dd.c") way back in 2005 to get code
out of drivers/base/bus.c.

Naming is hard :)
