BTW seems like wacom_get_report() got EPIPE and bailed out. We used to retry on EPIPE before aef3156d72. Would it make sense to retest with that commit reverted? Could be that the device is for some reason causing only temporary EPIPE that eventually gets fixed over time. I still don't exactly see how that'd cause the null pointer dereference later, but retval handling wacom_get_report() might possibly need some loving care as well, looking quickly at the code. But that still needs to be investigated.
