From 239552f495b91fc8f3fba4b5094233e053d265cb Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sun, 16 Oct 2016 17:06:20 -0700 Subject: [PATCH] hwmon: (core) Make is_visible callback truly mandatory The is_visible callback provides the sysfs attribute mode and is thus truly mandatory as documented. Check it once at registration and remove other checks for its existence.
