[Dell Latitude 2110] SD card reader not working

[Daniel Manrique]

This issue was observed in 3 Dell Latitude 2110 laptops with various specs, the common problem is that SD card reader is not working.

Steps to reproduce:
1- Install Ubuntu
2- Insert a SD card into the reader

Expected result:
- System detects and mounts the SD card, files are accessible.

Actual result:
- Nothing. No indication that the system even detects the card insertion. I don't even see a device in lspci that could be the card reader. So it's apparently not recognized at all.

I tested this with Natty kernel 2.6.38-8, also with a 2.6.35-28 kernel from Maverick and this mainline kernel:

http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2011-04-08-natty/linux-image-2.6.39-999-generic_2.6.39-999.201104080911_i386.deb

All exhibit the same behavior (i.e. nothing at all when inserting a card).

Support for the 5208 and 5209 Realtek cards has been added to the latest Natty kernel

[Herton R. Krzesinski (herton)]

The card reader on lspci should be this one:
0d:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device [10ec:5208] (rev 01)
 Subsystem: Dell Device [1028:0461]
 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx-
 Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
 Latency: 0, Cache Line Size: 64 bytes
 Interrupt: pin A routed to IRQ 3
 Region 0: Memory at f6bf0000 (32-bit, non-prefetchable) [size=64K]
 Capabilities: <access denied>

Indeed no string which makes easy to identify it :), I found it by the pci id, which new rts_pstor module that implements support for this card reader should handle. 2.6.38-8.41 on natty didn't have rts_pstor, but it was included in recently uploaded 2.6.38-8.42, can you update and test with it?

Ignore my last comment, I had this opened before it was marked as duplicate.

Confirming bug still exists in 3.13.0-24-generic kernel. Unable to use any SDCards in the reader.
Attached is lscpi -vvv output of the card reader on the dell I tested.
