Merge branch 'i2c/for-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
"Here is the I2C pull request for 4.8:
- the core and i801 driver gained support for SMBus Host Notify
- core support for more than one address in DT
- i2c_add_adapter() has now better error messages. We can remove all
error messages from drivers calling it as a next step.
- bigger updates to rk3x driver to support rk3399 SoC
- the at24 eeprom driver got refactored and can now read special
variants with unique serials or fixed MAC addresses.
The rest is regular driver updates and bugfixes"
