Error when loading wlan-sdio.ko

[aigFsch]

This is a followup to my question here: https://github.com/8devices/qcacld-2.0/issues/11

When I try to insmod my sdio driver it fails with the following message:

insmod /lib/modules/4.9.88-F\+S/wlan-sdio.ko
wlan_sdio: loading out-of-tree module taints kernel.

Do you have any idea what might lead to this error?

[valinskas]

Driver running on Host fails to communicate with SDIO device over SDIO bus. MMC/SDIO stack returns errors:

#define ETIMEDOUT       110     /* Connection timed out */
#define EILSEQ          84      /* Illegal byte sequence */

It can be many things from a hardware compatibility (SD Host and SD device), powering (V1.8 vs V3 mismatch) and etc. No activity over the year, closed issue.
