Merge branch 'i2c/for-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:

 - new drivers for Spreadtrum I2C, Intel Cherry Trail Whiskey Cove SMBUS

 - quite some driver updates

 - cleanups for the i2c-mux subsystem

 - some subsystem-wide constification

 - further cleanup of include/linux/i2c
