Subject: Linux 3.16: O2 Micro MMC missing in lspci

Hello,

when booting into 3.16.0-2-ARCH I miss the following
entry in lspci:

[12:50] gold:debug-sd-card-reader% diff 3.15/lspci 3.16/lspci 
17d16
< 03:00.0 SD Host controller: O2 Micro, Inc. SD/MMC Card Reader
Controller (rev 01)

This causes my system to be unable to mount/see the sd cards.
My hardware is a Dell E7440 notebook.

I attached dmesg & lspci of both kernels.

Anyone an idea on what might be wrong?

The only related issues I found is
    https://bugs.archlinux.org/task/26971

and that there was a change in the mmc area:

    https://lkml.org/lkml/2014/6/10/491

Cheers,

Nico
