   4 Subject: [PATCH 262/782] staging: bcm2835-camera: Correct
   5  V4L2_CID_COLORFX_CBCR behaviour
   6
   7 With V4L2_CID_COLORFX_CBCR calling ctrl_set_colfx it was incorrectly
   8 assigning the colour values to the enable field of dev->colourfx
   9 instead of the u and v fields.
  10
  11 Correct the assignments.
  12
  13 Reported as a Coverity issue
  14 Detected by CoverityScan CID#1419711 ("Unused value")
