Bug: cppcheck reported overflow in array assignment (for loop walks
0 to IOP_ADMA_NUM_SRC_TEST+2, array size is IOP_ADMA_NUM_SRC_TEST).
Reported as: https://bugzilla.kernel.org/show_bug.cgi?id=42677
Test code pq_src array was grown by two elements to correspond with actual
usage (IOP_ADMA_NUM_SRC_TEST+2), stack consumption was kept constant by
modifying the pq_dest two element array which is only used when pq_src
is referenced up to IOP_ADMA_NUM_SRC_TEST elements into the address
of the new last two elements of the pq_src array. This is presumed to
be the original intent but would be reliant on compilers always having
pq_dest contiguous with the final element of pq_src.
Note: This is a re-send of a request for review from two weeks ago.
Looking for review (or shootdown), adding LKML to list for a wider
audience. Thanks.
