From 273c868e85a56481ccb34822be2033dbe63248fb Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 29 Sep 2017 11:22:05 +0100 Subject: rtc: pl031: use devm_* for allocating memory and mapping resource Use the devm_* APIs for allocating memory and mapping the memory in the probe function to relieve the driver from having to deal with this in the cleanup paths.
