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 
ibmvnic: fix: NULL pointer dereference.
 
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.

Fixes: 9281cf2d5840 ("ibmvnic: avoid memset null scrq msgs")
