Bug description:
SRU Justification:
Impact: the card reader does not work on this system after rebooting.
Fix: cherry pick a simple one line patch
Testcase: already tested in OEM projects
CID: 201307-14017 Dell Latitude E5440
The O2 card reader, O2 Micro, Inc. SD/MMC Card Reader Controller [1217:8520] (rev 01)
is not stable on this system, the card reader cannot be detected.
It works normally after reboot, but will be gone if you reboot it one more time
Steps:
1. Install 14.04 + update (3.13.0-32), boot to desktop
2. Run lspci -nn to see if the card reader is there
3. Insert a SD card
4. Reboot, go through step 2 and 3 again
Expected result:
* Card reader should be found in lspci output, SD card should be mounted automatically
Actual result:
* Nothing happened, the card was not detected at all
* On step 4, the card reader works, if rebooted again, it will be gone.
