From 4861ee15f2b7dee17a869d9edd3463b812f77636 Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Tue, 8 Nov 2016 18:13:28 +0900 Subject: [PATCH] scsi: ufs: Use the resource-managed function to add devfreq device This patch uses the resource-managed to add the devfreq device. This function will make it easy to handle the devfreq device. - struct devfreq *devm_devfreq_add_device(struct device *dev, struct devfreq_dev_profile *profile, const char *governor_name, void *data); Cc: Vinayak Holikatti Cc: James E.J.
