Coverity issue: 254842 Uninitialized scalar variable The variable will contain an arbitrary value left from earlier computations.

In parse_page_descriptors: Use of an uninitialized variable (CWE-457) The elem.src variable is not initialized, but in dma_trace_host_buffer() the code reads this initialized value.

Break

*e = *elem;

in e->dest = elem->dest; e->size = elem->size;

to only access relevant fields.

Applied.
