From 09cf1b321ad353eeaeddcfd33771b34ce2a61640 Mon Sep 17 00:00:00 2001 From: Adriana Reus Date: Thu, 24 Mar 2016 11:29:30 +0200 Subject: [PATCH] iio: accel: kxcjk-1013: 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.
