Re: Odd hang on suspend and shutdown

Ok, if you can suspend after this modprobe we're looking at some
potential mei bus or mei core issues.

Just looking at the mei/bus.c code to match the driver, and it looks just odd.

Before the commit that breaks for me, it used to have this loop:

-       while (id->name[0]) {

and now it has

+       while (uuid_le_cmp(NULL_UUID_LE, uuid_le_cast(id->uuid))) {

which seems to mean that together with my change to make a working
kernel (just removing the UUID entirely) means that now the
device_driver isn't matched against anything at all any more.

So I'm not sure "modprobe pn544_mei" ends up actually triggering
anything at all with my change to make it not lock up for me.
