Merge patch series "tools: selftests: riscv: Fix compiler warnings"

From: Christoph Müllner <christoph.muellner@vrull.eu>

When building the RISC-V selftests with a riscv32 compiler I ran into
a couple of compiler warnings. While riscv32 support for these tests is
questionable, the fixes are so trivial that it is probably best to simply
apply them.

Note that the missing-include patch and some format string warnings
are also relevant for riscv64.

* b4-shazam-merge:
  tools: selftests: riscv: Fix compile warnings in mm tests
  tools: selftests: riscv: Fix compile warnings in vector tests
  tools: selftests: riscv: Add missing include for vector test
  tools: selftests: riscv: Fix compile warnings in cbo
  tools: selftests: riscv: Fix compile warnings in hwprobe
