This reverts commit 150b8be3cda54412ad7b54f5392b513b25c0aaa7.

The I2C core's per-adapter locks can't protect from IRQs, so the driver still
needs a spinlock to protect the register accesses.

Looks to me like a plain revert. What about the issues you mentioned?
Don't you want to fix them? Confused...

You told me to do 2 patches, one of them just revert. Here you are. As for the follow up patch, I need to think a bit more, so all in a good time.

WBR, Sergei
