Merge tag 'char-misc-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char/misc driver updates from Greg KH:
 "Here's the "big" char and misc driver update for 4.9-rc1.

  Lots of little things here, all over the driver tree for subsystems
  that flow through me. Nothing major that I can discern, full details
  are in the shortlog.

  All have been in the linux-next tree with no reported issues"

Contact: Christoph Mair <christoph.mair@gmail.com>
Description: Tell the bmp085 to use more samples to calculate a pressure
value. When writing to this file the chip will use 2^x samples
to calculate the next pressure value with x being the value
written. Using this feature will decrease RMS noise and
increase the measurement time.
Reading: returns the current oversampling setting.
Writing: sets a new oversampling setting.
Accepted values: 0..3.
