[ Upstream commit 65243386f41d38460bfd4375d231a7c0346d0401 ]
The vivid driver has two custom controls that change the behavior of RDS. Depending on the control setting the V4L2_CAP_READWRITE capability is toggled. However, after an earlier commit the capability was no longer set correctly. This is now fixed.
Fixes: 9765a32cd8 ("vivid: set device_caps in video_device")
