Subject: [PATCH v10 05/21] media: uvcvideo: Remove s_ctrl and g_ctrl
Date: Fri, 18 Jun 2021 14:29:07 +0200 [thread overview]
Message-ID: <20210618122923.385938-6-ribalda@chromium.org> (raw)
In-Reply-To: <20210618122923.385938-1-ribalda@chromium.org>
If we do not implement these callbacks the framework will call the
ext_ctrl callbaks instead, which are a superset of this functions.
