Yes, I considered creating a tag to pull already when sending out this series, but I guessed delaying that a little bit to give people the opportunity to ack would be a good idea. @broonie: Do you think this change is a good idea? Would you require some more acks for the preparatory patches? I had hoped to get Acks from the corresponding maintainers, maybe they are busy and missed this series as I put them on Cc: only. I promoted them to To: in this mail. Or is it too ambitious to get this in during the next merge window? Best regards Uwe

I was going to apply this but it needs rebasing against current code unfortunately.

The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.
