Merge tag 'auxdisplay-v7.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/andy...

Pull auxdisplay updates from Andy Shevchenko:

 - Fix potential out-of-bound access in line-display library

 - Miscellaneous refactoring and cleaning up

[ Andy says this could easily be delayed until 7.2, but it's _so_ tiny
  that it's more work for me to schedule it for later than to just take
  it now, and just doesn't seem worth delaying    - Linus ]
