Subject: [PATCH v4 0/3] return EINVAL error instead of BUG_ON()

This patch series makes driver_register() emit an error message and
return a failure code instead of triggering a BUG_ON().

The first patch will now print out the name of the faulty driver *and*
the name of the involved bus. The second patch records the error code
if bus_register() fails. The third and final patch of the series
extends the first patch so that the recorded error code is also print
out if non-zero. Otherwhise, if drv->bus->p is NULL but the error code
is zero, then probably bus_register() was never called before.

Florian Schmaus (3):
  driver-core: return EINVAL error instead of BUG_ON()
  driver-core: record error on bus registration
  driver-core: print bus registration error value
