Title:
  [Lenovo ThinkPad T420] Borked Ricoh SD card reader e823; device
  misidentifies as e822 after system reboot

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  After starting Ubuntu 11.10 up once, lspci -nn shows:
  0d:00.0 System peripheral [0880]: Ricoh Co Ltd Device [1180:e823] (rev 08)

  After a reboot, lspci -nn shows:
  0d:00.0 System peripheral [0880]: Ricoh Co Ltd MMC/SD Host Controller [1180:e822] (rev 08)

  Card reader functionality still appears to work in Linux.  However,
  rebooting to Windows after using Linux breaks card reader
  functionality there (Windows complains about a driver not found
  issue).  Card reader works in Windows if I have not rebooted from
  Linux.
