The commit 52c4dfcead49 ("Staging: vc04_services: Cleanup in
|
||||
ctrl_set_bitrate()") changed the return behavior of ctrl_set_bitrate().
|
||||
This breaks probing of bcm2835-camera:
|
||||
|
||||
bcm2835-v4l2: mmal_init: failed to set all camera controls: -3
|
||||
Cleanup: Destroy video encoder
|
||||
Cleanup: Destroy image encoder
|
||||
Cleanup: Destroy video render
|
||||
Cleanup: Destroy camera
|
||||
bcm2835-v4l2: bcm2835_mmal_probe: mmal init failed: -3
|
||||
bcm2835-camera: probe of bcm2835-camera failed with error -3
|
||||
|
||||
So restore the old behavior and fix this issue.
