If anyone has any objections, please let me know. ------------------ commit 5fb2c782f451a4fb9c19c076e2c442839faf0f76 upstream. This device automatically switches itself to another mode (0x1405) unless the specific access pattern of Windows is followed in its initial mode. That makes a dirty unmount of the internal storage devices inevitable if they are mounted. So the card reader of such a device should be ignored, lest an unclean removal become inevitable. This replaces an earlier patch that ignored all LUNs of this device. That patch was overly broad.
