Subject: [PATCH 1/3] staging: rtl8723bs: remove unused function ODM_InbandNoise_Monitor
Date:   Fri, 19 Aug 2022 11:35:35 +0200
Message-Id: <46d73e331bae2192a328f6691763f39ea6c18b08.1660901124.git.namcaov@gmail.com>
In-Reply-To: <cover.1660901124.git.namcaov@gmail.com>
References: <cover.1660901124.git.namcaov@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

because this function is not used. Also remove function
odm_InbandNoise_Monitor_NSeries because it is a static function
which is only called from ODM_InbandNoise_Monitor.
