Merge patch series "lib: uuid: fix uuid_str_to_le_bin() on 32-bit"
Heinrich Schuchardt <heinrich.schuchardt@canonical.com> says: The lib_test_uuid_to_le and lib lib_test_dynamic_uuid tests fail on 32-bit systems. But we never caught this in our CI because we never ran any of our C unit tests on 32-bit. Enable CONFIG_UNIT_TEST on qemu_arm_defconfig. hextoul() cannot convert a string to a 64-bit number on a 32-bit system. Use the new function hextoull() instead.
