[PULL REQUEST] i2c-for-7.1-rc1-part1

Linus,
the biggest news in this pull request is that it will start the last
cycle of me handling the I2C subsystem. From 7.2. on, I will pass
maintainership to Andi Shyti who has been maintaining the I2C drivers
for a while now and who has done a great job in doing so. We will use
this cycle for a hopefully smooth transition, Thanks must go to Andi for
stepping up! I will still be around for guidance.
Thanks and please pull!
