Pull i2c fixes from Wolfram Sang:
 "Improve the detection when to run atomic transfer handlers for kernels
  with preemption disabled. This removes some false positive splats a
  number of users were seeing if their driver didn't have support for
  atomic transfers.

  Also, fix a typo in the docs while we are here"
