Could you apply this patch and see what it shows:

diff --git a/drivers/mmc/core/sdio_cis.c b/drivers/mmc/core/sdio_cis.c
index d5e51b1..60ec4d3 100644

ret = cistpl_funce_common(card, buf, size);

if (ret) {
- printk(KERN_ERR "%s: bad CISTPL_FUNCE size %u "
- "type %u\n", mmc_hostname(card->host), size, buf[0]);

return ret;
}

Again that would be good to know if/when func is NULL when those are
parsed.

Most probably not.
