@ -539,3 +539,13 @@ When: 3.6
Why: setitimer is not returning -EFAULT if user pointer is NULL. This
violates the spec.
Who: Sasikantha Babu <sasikanth.v19@gmail.com>
----------------------------
What: V4L2_CID_HCENTER, V4L2_CID_VCENTER V4L2 controls
When: 3.7
Why: The V4L2_CID_VCENTER, V4L2_CID_HCENTER controls have been deprecated
for about 4 years and they are not used by any mainline driver.
There are newer controls (V4L2_CID_PAN*, V4L2_CID_TILT*) that provide
similar functionality.
