## Name

drm_noop — 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.
