From 27971335ce666feb08344ca7c5fdd25f13985f62 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 29 Apr 2013 16:19:10 -0700 Subject: [PATCH] rtc: rtc-palmas: use devm_rtc_device_register() and devm_request_threaded_irq() devm_rtc_device_register() is device managed and makes cleanup paths simpler. Also, use devm_request_threaded_irq() to make cleanup paths more simple.
