From 969fdd86caa5be3e57d9e4b6ba4541ec5a54eae8 Mon Sep 17 00:00:00 2001 From: Rodrigo Carvalho Date: Sat, 7 Dec 2019 01:53:38 -0300 Subject: [PATCH] staging: iio: accel: adis16240: enforce SPI mode on probe function According to the datasheet, this driver supports only SPI mode 3, so we should enforce it on probe function.
