Subject: [PATCH 03/14] staging: rtl8192e: Remove IS_DOT11D_ENABLE(ieee)
Message-ID: <9e737b2246e0b73c3ad84a4ee09f5e94bf778b3c.1700431464.git.philipp.g.hortmann@gmail.com>

Content-Disposition: inline
In-Reply-To: <cover.1700431464.git.philipp.g.hortmann@gmail.com>
Precedence: bulk

Variable "enabled" is initialized to false and never changed. Therefore
IS_DOT11D_ENABLE(ieee) returns always false. Remove dead code.
