From 9d482aedd0e2389b483ea8ea727ec201b65e2f27 Mon Sep 17 00:00:00 2001 From: Alexander Shishkin Date: Fri, 4 Mar 2016 19:55:10 +0200 Subject: [PATCH] intel_th: msu: Create sysfs attributes using core driver's facility The core intel_th driver allows subdevices to bring in their sysfs attributes. Use this instead of taking care of them in probe and remove.
