I own a Lenovo Thinkpad T440s as well just as the original bug submitter
(Philipp) and that patch by Wei does not fix the problem for me (I applied it
to a 3.18 tree).
What does work is to follow Philipp's instructions to patch the out-of-tree
driver from realtek.com.tw. That module then gives me my SD card as /dev/sdbX.
Weirdly, my SD card reader used to work (but presented the SD card as
/dev/mmcblk0pX). I do not know why it stopped working though as I didn't reboot
my laptop for several months. Running an older kernel version (3.14 for
example) does not fix the problem. Maybe it is related to other parts of my
(Debian testing) OS. I'll see if I can find a Debian unstable snapshot that
restores the behaviour I observed last year and try to bisect to find the
source of the regression.
Thanks!
cheers, josch
