   4 Subject: [PATCH] staging: bcm2835-camera: Correct ctrl
   5  min/max/step/def to 64bit
   6
   7 The V4L2 control API was expanded to take 64 bit values in commit
   8 0ba2aeb6dab (Apr 16 2014), but as this driver wasn't in the mainline
   9 kernel at that point this was overlooked.
  10
  11 Update to use 64 bit values. This also fixes a couple of warnings
  12 in 64 bit builds.
