From 87e715deb8e24bf1a6a9a1babaf465c28c93889c Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Tue, 14 Feb 2017 12:24:09 -0800 Subject: zorro: stop creating attributes by hand Instead of creating attributes one by one, define attribute_group array and attach it to bus->dev_groups, so that all needed attributes are created automatically when a new device is registered on the bus. Also switch to using standard DEVICE_ATTR_RO() macros.
