Subject: [PATCH v2 18/18] media: i2c: max9286: Rework comments in .bound()
Date: Mon, 15 Mar 2021 14:15:12 +0100 [thread overview]
Message-ID: <20210315131512.133720-19-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <20210315131512.133720-1-jacopo+renesas@jmondi.org>
Re-phrase a comment in .bound() callback to make it clear we register
a subdev notifier and remove a redundant comment about disabling i2c
auto-ack.
No functional changes intended.
