From ee8c5419e06e3a002995f5d1f57c9b5aead331e6 Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Thu, 24 Mar 2016 11:29:28 +0200 Subject: [PATCH] iio: gyro: bmg160: use available_scan_masks Use available_scan_masks to allow the iio core to select the data to send to userspace depending on which axes are enabled, instead of doing this in the driver's interrupt handler.
