[PATCH v3 3/6] platform/chrome: cros_ec_sysfs: use permission-specific DEVICE_ATTR variants

From: Enric Balletbo i Serra
Date: Tue Mar 20 2018 - 11:52:34 EST


Use DEVICE_ATTR variants for read/write attributes. This simplifies the
source code, improves readbility, and reduces the chance of
inconsistencies.
