Gabriel Krisman Bertazi 8817b44aa9 drm: panel-orientation-quirks: Do rotation quirk for new GPD Win2 FW
I just got a new GDP Win2 device with an updated firmware, which still
requires this quirk to get the rotation right, so add the new firmware
date to the quirk matching table.

This should go to drm-misc-next.

/**
* 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.
