drm_noop(9) 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.
