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