Subject: [PATCH 2/2] power: supply: axp20x_battery: Use scaled iio_read_channel
Date: Wed, 23 Oct 2024 13:48:00 -0500	[thread overview]
Message-ID: <20241023184800.109376-3-macroalpha82@gmail.com> (raw)
In-Reply-To: <20241023184800.109376-1-macroalpha82@gmail.com>

From: Chris Morgan <macromorgan@hotmail.com>

Change iio_read_channel_processed to iio_read_channel_processed_scale
where appropriate.
