Subject: [PATCH 0/2] driver core: Improve warning backtrace in device probing

	Hi Greg, Rafael,

Once in a while, the WARN_ON() in really_probe() is triggered due to a
bug in a driver or subsystem.  While the backtrace provides some clues,
it does not reveal the offending device.

Hence this patch series adds a new dev_WARN_ON() helper, and uses that.

Thanks!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
