Subject: [PATCH 1/6] staging: rtl8192e: Remove unchanged variable
 dig_enable_flag
Message-ID: <24a9245840093c5a14124f9fc896433c7d85d18c.1697127817.git.philipp.g.hortmann@gmail.com>

Content-Disposition: inline
In-Reply-To: <cover.1697127817.git.philipp.g.hortmann@gmail.com>
Precedence: bulk

Remove variable dig_enable_flag as its value is set to 1 at
initialization. No further writes to dig_enable_flag are done. The
equations result accordingly. Remove dead code.
