Subject: [PATCH 1/3] Revert "driver core: Export device_is_dependent() to
 modules"

This reverts commit 1d5e8f4bf06da86b71cc9169110d1a0e1e7af337.

Greg says: "why exactly is this needed?  Nothing outside of
the driver core should be needing this function, it shouldn't
be public at all (I missed that before.)

So please, revert it for now, let's figure out why DRM thinks
this is needed for it's devices, and yet no other bus/subsystem
does."
