Subject: [PATCH v2 3/4] media: v4l2-async: Call post_register() subdev op
Date: Wed, 7 Jul 2021 17:20:02 +0200 [thread overview]
Message-ID: <20210707152003.136272-4-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <20210707152003.136272-1-jacopo+renesas@jmondi.org>
Call the "post_register()" subdev operation on a just registered
subdevice, immediately after having called the 'bound' notifier
operation on the parent.
