Revision 862aecbd9569e563b979c0e23a908b43cda4b0b9 authored by YANG LI on 30 December 2020, 07:23:14 UTC, committed by Jakub Kicinski on 04 January 2021, 21:23:33 UTC
The error is due to dereference a null pointer in function reset_one_sub_crq_queue(): if (!scrq) { netdev_dbg(adapter->netdev, "Invalid scrq reset. irq (%d) or msgs(%p).\n", scrq->irq, scrq->msgs); return -EINVAL; } If the expression is true, scrq must be a null pointer and cannot dereference.
