Subject: [PATCH AUTOSEL 6.0 05/34] media: rkisp1: Zero v4l2_subdev_format fields in when validating links
Date: Tue, 1 Nov 2022 07:26:57 -0400 [thread overview]
Message-ID: <20221101112726.799368-5-sashal@kernel.org> (raw)
In-Reply-To: <20221101112726.799368-1-sashal@kernel.org>
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
[ Upstream commit c53e3a049f35978a150526671587fd46b1ae7ca1 ]
The local sd_fmt variable in rkisp1_capture_link_validate() has
uninitialized fields, which causes random failures when calling the
subdev .get_fmt() operation. Fix it by initializing the variable when
declaring it, which zeros all other fields.
