Merge branch 'i2c/for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "Highlights:

   - class based instantiation finally dropped for most embedded drivers
     bringing boot up performance gains
   - removed two drivers (one outdated, one a duplicate)
   - ACPI has now operation region support (thanks to Lan Tianyu)
   - the i2c-stub driver got overhauled and gained new features to
     become more useful when writing i2c client drivers (thanks to
     Guenter Roeck and Jean Delvare)

  The rest is driver bugfixes, added bindings/ids, cleanups..."
