Description:
Looks like the latest kernel stop to recognize sd cards.

My internal reader seems to be recognized as shown in dmesg:

[ 7.745263] sdhci: Secure Digital Host Controller Interface driver
[ 7.745267] sdhci: Copyright(c) Pierre Ossman
(...)
[ 8.140405] sdhci-pci 0000:08:05.2: SDHCI controller found [1217:7120] (rev 2)
[ 8.140428] sdhci-pci 0000:08:05.2: PCI INT A -> GSI 22 (level, low) -> IRQ 22
[ 8.140510] _regulator_get: 0000:08:05.2 supply vmmc not found, using dummy regulator
[ 8.140572] Registered led device: mmc0::
[ 8.140636] mmc0: SDHCI controller on PCI [0000:08:05.2] using DMA

lspci -k shows the reader:

08:05.2 SD Host controller: O2 Micro, Inc. Integrated MMC/SD Controller (rev 02)
Subsystem: Dell Device 0273
Kernel driver in use: sdhci-pci
Kernel modules: sdhci-pci

But when I plug any SD card, nothing occurs, nothing in the logs too.

My notebook is a Dell Vostro 1510, and I tried to use Windows Vista and the card does not opens too, then I call Dell support and they told me to upgrade the BIOS, SD and chipset drivers, after that the card started to work again, just in Windows Vista... =(

Additional info:
* package version(s)
uname -r
3.1.1-1-ARCH

* config and/or log files etc.


Steps to reproduce:

Try to open any SD card in Dell Vostro 1510 with the latest kernel from Arch Linux.
