[PULL REQUEST] i2c for 3.10
From: Wolfram Sang

Linus,
please pull the i2c changes for 3.10. Highlights:
* an arbitration driver. While the driver is quite simple, it caused
discussion if we need additional arbitration on top of the one
specified in the I2C standard. Conclusion is that I accept a few
generic mechanisms, but not very specific ones.
* the core lost the detach_adapter() call. It has no users anymore
and was in the way for other cleanups. attach_adapter() is sadly
still there since there are users waiting to be converted.
* the core gained a bus recovery infrastructure. I2C defines a way
to recover if the data line is stalled. This mechanism is now in the
core and drivers can now pass some data to make use of it.
* bigger driver cleanups for designware, s3c2410
* removing superfluous refcounting from drivers
* removing Ben Dooks as second maintainer due to inactivity. Thanks
for all your work so far, Ben!
* bugfixes, feature additions, devicetree fixups, simplifications...
Thanks,
Wolfram
