From 54a19fd4a6402ef47fce5c3a5374c71f52373c40 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 13 Nov 2019 16:23:06 +0100 Subject: [PATCH] i2c: core: Use DEVICE_ATTR_*() helper macros Convert the i2c core sysfs attributes from DEVICE_ATTR() to DEVICE_ATTR_*(), to reduce boilerplate. This requires renaming some functions. Although no suitable macro exists for the delete_device attribute, rename i2c_sysfs_delete_device() to delete_device_store() for consistency.
