Subject: [PATCH 07/16] video: vpl: fix potential read of uninitialized variable
Date: Thu, 5 Jun 2025 23:07:17 +0200 [thread overview]
Message-ID: <20250605210726.1916656-8-a.fatoum@barebox.org> (raw)
In-Reply-To: <20250605210726.1916656-1-a.fatoum@barebox.org>
remote_port_id is passed to the ioctl callback, so make sure it has a
