Hmm, the rationale behind your change to make the pdata allocation
per-device in ("coresight: trbe: Allocate platform data per device")
confuses me: with Anshuman's change to allocate the pdata using
devm_kzalloc(), there shouldn't be any connections for the coresight
core to trip over, should there?

It would've been nice to know about the conflict earlier, but since I
think you're away this week and we're likely to hit the merge window
next week, I'm going to drop the coresight patches for now.
