Pull char/misc patches from Greg KH:
 "Here's the big char/misc driver patchset for 3.13-rc1.

  Lots of stuff in here, including some new drivers for Intel's "MIC"
  co-processor devices, and a new eeprom driver.  Other things include
  the driver attribute cleanups, extcon driver updates, hyperv updates,
  and a raft of other miscellaneous driver fixes.

  All of these have been in linux-next for a while"
