Subject: [PATCH 02/13] iio: imu: inv_mpu6050: delete useless check
Date: Wed, 12 Feb 2020 18:40:37 +0100
Message-ID: <20200212174048.1034-3-jmaneyrol@invensense.com> (raw)
In-Reply-To: <20200212174048.1034-1-jmaneyrol@invensense.com>

If we are here it means we have fifo enabled for 1 sensor
at least. And interrupt is always required for using trigger.
