Subject: [PATCH] staging: greybus: codecs: use dedicated list iterator variable
Date: Mon, 21 Mar 2022 13:37:12 +0100 [thread overview]
Message-ID: <20220321123712.3068778-1-jakobkoschel@gmail.com> (raw)
In preparation to limit the scope of the list iterator to the list
traversal loop, use a dedicated pointer to point to the found element [1].
