58 * - GET_UNIQUE ioctl, implemented by drm_getunique is wrapped up in libdrm
60 * - The libdrm drmSetBusid function is backed by the SET_UNIQUE ioctl. All
63 * exclusively use by the SET_VERSION ioctl, because only drm 1.0 (which is
64 * nerved) allowed userspace to set the busid through the above ioctl.
86 * name returned by that ioctl. Note that SET_VERSION is not called, which
189 * Hollowed-out getclient ioctl to keep some dead old drm tests/tools

432 * @data: data pointer for the ioctl
433 * @file_priv: DRM file for the ioctl call
