  19 * Some x86 clamshell design devices use portrait tablet screens and a display
  20 * engine which cannot rotate in hardware, so we need to rotate the fbcon to
  21 * compensate. Unfortunately these (cheap) devices also typically have quite
  22 * generic DMI data, so we match on a combination of DMI data, screen resolution
  23 * and a list of known BIOS dates to avoid false positives.

 255 * This function checks for platform specific (e.g. DMI based) quirks
 256 * providing info on panel_orientation for systems where this cannot be
 257 * probed from the hard-/firm-ware. To avoid false-positive this function

 262 * the efifb code. Because of this this function gets compiled into its own
 263 * kernel-module when built as a module.
 264 *

 267 * or DRM_MODE_PANEL_ORIENTATION_UNKNOWN if there is no quirk.
