Peter, thank you! I agree with you that
as mentioned in the documentation
https://docs.amd.com/r/en-US/ug1085-zynq-ultrascale-trm/ADDR_EXT-Field,
we should take 32 bits of the address from one field
(for example, case 1, SRC_ADDR2_EXT - in code it is desc->source_address2)
and 16 bits (high or low

Overflow can occur in a situation where desc->source_address
has a maximum value (pow(2, 32) - 1), so add a cast to a
larger type before the assignment.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
