Merge branch 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c fixes from Wolfram Sang:

 - a small collection of remaining API conversion patches (all acked)
   which allow to finally remove the deprecated API

 - some documentation fixes and a MAINTAINERS addition
