Pull char/misc driver updates from Greg KH:
 "Here is the big set of new char/misc driver drivers and features for
  4.12-rc1.

  There's lots of new drivers added this time around, new firmware
  drivers from Google, more auxdisplay drivers, extcon drivers, fpga
  drivers, and a bunch of other driver updates. Nothing major, except if
  you happen to have the hardware for these drivers, and then you will
  be happy :)

  All of these have been in linux-next for a while with no reported
  issues"

* flags: Reserved for future use, this field is expected to be

*
* addr: Address on the host LPC bus that the specified window should
* be mapped. This address must be power of two aligned.
*
* offset: Offset into the BMC window that should be mapped to the
* host (at addr). This must be a multiple of size.
*
* size: The size of the mapping. The smallest possible size is 64K.
* This must be power of two aligned.
