Subject: [PATCH 08/13] module: remove each_symbol_in_section
Date:   Tue,  2 Feb 2021 13:13:29 +0100
Message-Id: <20210202121334.1361503-9-hch@lst.de>
In-Reply-To: <20210202121334.1361503-1-hch@lst.de>
References: <20210202121334.1361503-1-hch@lst.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

each_symbol_in_section just contains a trivial loop over its arguments.
Just open code the loop in the two callers.
