/**
* struct drm_mode_get_connector - Get connector metadata.
*
* User-space can perform a GETCONNECTOR ioctl to retrieve information about a
* connector. User-space is expected to retrieve encoders, modes and properties
* by performing this ioctl at least twice: the first time to retrieve the
* number of elements, the second time to retrieve the elements themselves.
*
* To retrieve the number of elements, set @count_props and @count_encoders to
* zero, set @count_modes to 1, and set @modes_ptr to a temporary struct
* drm_mode_modeinfo element.
*
* To retrieve the elements, allocate arrays for @encoders_ptr, @modes_ptr,
* @props_ptr and @prop_values_ptr, then set @count_modes, @count_props and
* @count_encoders to their capacity.
*
* Performing the ioctl only twice may be racy: the number of elements may have
* changed with a hotplug event in-between the two ioctls. User-space is
* expected to retry the last ioctl until the number of elements stabilizes.
* The kernel won't fill any array which doesn't have the expected length.
*
* **Force-probing a connector**
*
* If the @count_modes field is set to zero, the kernel will perform a forced
* probe on the connector to refresh the connector status, modes and EDID.
* A forced-probe can be slow and the ioctl will block. A force-probe can cause
* flickering and temporary freezes, so it should not be performed
* automatically.
*
* User-space shouldn't need to force-probe connectors in general: the kernel
* will automatically take care of probing connectors that don't support
* hot-plug detection when appropriate. However, user-space may force-probe
* connectors on user request (e.g. clicking a "Scan connectors" button, or
* opening a UI to manage screens).
