* New patch to fix error handling sequence in probe.

v3:
* Fix build warnings reported by kbuild test bot.

Resend:
* Rebase to latest linux-next.
* Collect Acked-bys

v2:
* Drop DT patches. Will be sent as separate series as requested by
 maintainer.
* Split binding docs into separate patches.
* Address comments by Rob Herring.
