Char/Misc driver fixes for 4.8-rc5

Browse Source 
Here are a number of small driver fixes for 4.8-rc5.
 
 The largest thing here is deleting an obsolete driver,
 drivers/misc/bh1780gli.c, as the functionality of it was replaced by an
 iio driver a while ago.  The other fixes are things that have been
 reported, or reverts of broken stuff (the binder change).  All of these
 changes have been in linux-next for a while with no reported issues.
