449 * drm_get_panel_orientation_quirk - Check for panel orientation quirks
450 * @width: width in pixels of the panel
451 * @height: height in pixels of the panel
452 *
453 * This function checks for platform specific (e.g. DMI based) quirks
454 * providing info on panel_orientation for systems where this cannot be
455 * probed from the hard-/firm-ware. To avoid false-positive this function
456 * takes the panel resolution as argument and checks that against the
457 * resolution expected by the quirk-table entry.
458 *
459 * Note this function is also used outside of the drm-subsys, by for example
460 * the efifb code. Because of this this function gets compiled into its own
461 * kernel-module when built as a module.
462 *
463 * Returns:
464 * A DRM_MODE_PANEL_ORIENTATION_* value if there is a quirk for this system,
465 * or DRM_MODE_PANEL_ORIENTATION_UNKNOWN if there is no quirk.
