DRM no-op ioctl implemntation
Synopsis
int drm_noop ( | struct drm_device * dev, |
| | void * data, |
| | struct drm_file * file_priv); |
Arguments
dev
DRM device for the ioctl
data
data pointer for the ioctl
file_priv
DRM file for the ioctl call
Description
This no-op implementation for drm ioctls is useful for deprecated
functionality where we can't return a failure code because existing userspace
checks the result of the ioctl, but doesn't care about the action.
Always returns successfully with 0.
