[PATCH 2/5] iio: core: use permission specific variants of DEVICE_ATTR

From: Aishwarya Pant
Date: Thu Jan 04 2018 - 09:37:47 EST


This is a clean-up patch which replaces DEVICE_ATTR macro with the file
permission specific DEVICE_ATTR_{RO/WO/RW} macros for compaction and
readability. Done using coccinelle.
