+Subject: iio: adc: ad7606_spi: fix reg write value mask
+
+From: David Lechner <dlechner@baylibre.com>
+
+commit 89944d88f8795c6c89b9514cb365998145511cd4 upstream.
+
+Fix incorrect value mask for register write. Register values are 8-bit,
+not 9. If this function was called with a value > 0xFF and an even addr,
+it would cause writing to the next register.
+
+Fixes: f2a22e1e172f ("iio: adc: ad7606: Add support for software mode for ad7616")
