Subject: [PATCH] tests: subsys: logging: Test with CONFIG_LOG disabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Developer reports build error when he uses LOG_RAW in his code
and disables logging in prj.conf using CONFIG_LOG=n.

Add test case for above described scenario.
