From e8644e4c2aa5c52c357f63af9cc17ef5dce38396 Mon Sep 17 00:00:00 2001 From: Alexander Shishkin Date: Fri, 4 Mar 2016 19:55:10 +0200 Subject: intel_th: pti: 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.
