Subject: [PATCH v8 11/22] counter: Rename counter_signal_value to counter_signal_level
Date: Fri, 12 Feb 2021 21:13:35 +0900 [thread overview]
Message-ID: <c07454c388991d7e2432c1ef838405c9df9dd02f.1613131238.git.vilhelm.gray@gmail.com> (raw)
In-Reply-To: <cover.1613131238.git.vilhelm.gray@gmail.com>
Signal values will always be levels so let's be explicit it about it to
make the intent of the code clear.
