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