Subject: selftests/mqueue: fix 5 warnings about signed/unsigned mismatches
Date: Mon, 27 May 2024 13:08:35 -0700
When building with clang, via:
make LLVM=1 -C tools/testing/selftest
...clang warns about several cases of using a signed integer for the
priority argument to mq_receive(3), which expects an unsigned int.
Fix this by declaring the type as unsigned int in all cases.
