   4 Subject: [PATCH] uapi/v4l2-controls: Reset
   5  V4L2_CID_USER_BCM2835_ISP_BASE to same as 5.10
   6
   7 https://github.com/raspberrypi/linux/issues/4440
   8
   9 Upstream has added additional device specific controls, so the
  10 V4L2_CID_USER_BASE + 0x10e0 value that had been defined for use with
  11 the ISP has been taken by something else (and +0x10f0 has been used as
  12 well)
  13
  14 Duplicate the use on V4L2_CID_USER_BASE + 0x10e0 so that userspace
  15 (libcamera) doesn't need to change. Once the driver is upstream, then
  16 we'll update libcamera to adopt the new value as it then won't change.
