From 4546813a7f6b3dc67ac258666092b1952c4e2ea1 Mon Sep 17 00:00:00 2001 From: Brian Masney Date: Fri, 29 Sep 2017 21:09:20 -0400 Subject: staging: iio: tsl2x7x: migrate in_illuminance0_integration_time sysfs attribute to iio_chan_spec The driver explicitly creates the in_illuminance0_integration_time sysfs attribute outside the IIO core. This attribute is available in the IIO core so this patches migrates the attribute to be created by the iio_chan_spec.
