Subject: [PATCH 4/6] staging: rtl8192e: Remove unchanged variable
 dig_algorithm_switch
Message-ID: <a76d8b86f2591446a071b4f614adf628b0fe5c93.1697127817.git.philipp.g.hortmann@gmail.com>

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

Remove variable dig_algorithm_switch as its value is set to 0 at
initialization. The equations result accordingly. Remove dead code.
