Subject: [Patch 06/13] media: am437x-vpfe: Setting STD to current value is not an error
Date: Mon, 9 Sep 2019 11:27:36 -0500 [thread overview]
Message-ID: <20190909162743.30114-7-bparrot@ti.com> (raw)
In-Reply-To: <20190909162743.30114-1-bparrot@ti.com>
VIDIOC_S_STD should not return an error if the value is identical
to the current one.
This error was highlighted by the v4l2-compliance test.
