Hi,

I'm running linus master and can't load the libertas module for the
sd8686 wifi hardware in the OLPC XO-1.5 laptop.
Probe fails with -16.

dmesg and config:
http://dev.laptop.org/~dsd/20101031/dmesg-sdio-probe-fail.txt
http://dev.laptop.org/~dsd/20101031/config-sdio-probe-fail.txt

I've done some initial investigation; in sdio_bus_probe() we do this:
	ret = pm_runtime_get_sync(dev);
	if (ret < 0)
		goto out;

and pm_runtime_get_sync() returns -16
