Subject: [PATCH 2/5] iio: hid-sensor-als: Support change sensitivity in illuminance too.
Date: Sat, 27 Feb 2021 17:26:40 -0800 [thread overview]
Message-ID: <20210228012643.69944-3-ronald@innovation.ch> (raw)
In-Reply-To: <20210228012643.69944-1-ronald@innovation.ch>
Recent MacBook Pro's specify the usage of the change sensitivity field
as illuminance (with a change sensitivity modifier) rather than as
light.
