SD card reader not working

My card reader stopped working one day after an update, and after some kernel downgrades I got the version 4.9.11 as the latest linux kernel on which my card reader works.

On linux <= 4.9.11

There's no mmc_host under /sys/devices/pci0000:00/0000:00:12.0/

I tried rebinding the driver manually and reloading, but the mmc_host doesn't show up.
Also is noticeable that on the udev info on linux>4.9.11 there's no "E: DRIVER" field.
