Subject: [PATCH 4/6] staging: rtl8192e: Remove ant_pwr_diff which is always zero
Date: Fri, 20 Jan 2023 21:18:19 +0100	[thread overview]
Message-ID: <a550004dcdeb9e0b716f69033a541457c1f12c86.1674244819.git.philipp.g.hortmann@gmail.com> (raw)
In-Reply-To: <cover.1674244819.git.philipp.g.hortmann@gmail.com>

ant_pwr_diff is set to zero and then masked which will always result in
zero. Remove ant_pwr_diff and use zero direct as it is just useless
code.
