Subject: [Regression, post-3.5] NULL pointer dereference in usb-wwan after resume from system suspend

Hi,

The usb-wwan driver triggers a NULL pointer dereference oops after resume
from system suspend on my Toshiba Portege R500, but since that driver
hasn't changed since v3.5 and it is only used by the option driver, I suppose
that the latter is responsible for that.

This is a clear regression from v3.5, it hasn't happened ever before.

I'll collect some details tomorrow.

Thanks,
Rafael
