Subject: [PATCH 1/2] media: i2c: max96714: add HAS_EVENTS subdev flag
Date: Tue, 10 Sep 2024 15:44:27 +0200	[thread overview]
Message-ID: <20240910134428.795273-2-tomm.merciai@gmail.com> (raw)
In-Reply-To: <20240910134428.795273-1-tomm.merciai@gmail.com>

Controls can be exposed to userspace via a v4l-subdevX device, and
userspace has to be able to subscribe to control events so that it is
notified when the control changes value. Add missing HAS_EVENTS flag.
