Subject: [PATCH 28/45] image: Correct strncpy() warning with image_set_name()
Date: Sun, 25 Sep 2022 09:02:31 -0600 [thread overview]
Message-ID: <20220925150248.2524421-29-sjg@chromium.org> (raw)
In-Reply-To: <20220925150248.2524421-1-sjg@chromium.org>
gcc 12 seems to warn on strncpy() as a matter of course. Rewrite the code
a different way to do the same thing, to avoid the warning.
