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

Pull more i2c updates from Wolfram Sang:
 "Here is the second pull request from I2C for this merge window:

   - one new feature (which nearly fell through the cracks): i2c-dev
     does now use the cdev API so it can handle >256 minors.  Seems
     people do need that.

   - two fixes for the just added DMA feature for i2c-rcar

   - some typo fixes"
