Subject: sdio: bad CISTPL_FUNCE error

Hi Pierre,

While trying to setup a GPS SDIO card, I experience the following error: 
"mmc0: bad CISTPL_FUNCE size 28 type 1"

I use a combo card but without mirco sd card inserted.
http://www.spectec.com.tw/sdg810.htm

Tracing in sdio_cis.c file, I print the tpl_code (line 216).
I have 3 successive codes : 0xff, 0x21 & 0x22.

Is this a host controller driver issue ? or the using of a non 
supported combo SDIO card (with GPS function not probed first) ?


Here is a little log :
