You can add the above tag to all patches in your branch
'4.11-rc3-i2c-irq-resources' and after that we declare it immutable and
I'll pull it into my for-next. Sorry for the delay. I got side-tracked
and ill. But I am better now.

And to keep your heads up: We agreed yesterday that i2c_drivers will get
a flag to signal I2C core to skip all the irq assignment stuff and let
the driver do it itself [1]. Maybe this will become useful for you, too.
