usb multicardreader probes only first slot after update

[Wolfgang Zenker]

Hi,

I just noticed that a usb multicardreader that I have used for a few years
stopped working after an update from 8-STABLE around January 10th to
8-STABLE from May 29th. Reason appears to be that now only the first
slot (which is empty) is probed instead of all four slots like before.

dmesg output from after the update:

I have not yet tried what happens if I actually put a CF card in the reader
(that would be the first slot).
