Subject: [PATCH 0/2] media: i2c: max96714/max96717
Date: Tue, 10 Sep 2024 15:44:26 +0200 [thread overview]
Message-ID: <20240910134428.795273-1-tomm.merciai@gmail.com> (raw)
Hi All,
This patchset add missing HAS_EVENTS flags to max96714/max96717 drivers.
"If HAS_DEVNODE is set, and there are controls, then HAS_EVENTS
must be set and you have to be able to (un)subscribe to events.
Because the 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."

Tommaso
