Subject: [PATCH] drm: atomic helper: fix W=1 warnings
Date: Mon, 9 Sep 2019 15:52:05 +0200 [thread overview]
Message-ID: <20190909135205.10277-2-benjamin.gaignard@st.com> (raw)
In-Reply-To: <20190909135205.10277-1-benjamin.gaignard@st.com>
Fix warnings with W=1.
Few for_each macro set variables that are never used later.
Prevent warning by marking these variables as __maybe_unused.
