From 1b3493d755c85b0fd206b7e5f04ce7050af90c41 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Thu, 6 Sep 2018 17:55:25 +0200 Subject: clk: samsung: s3c2412: Use generic helper for handling suspend/resume Replace common suspend/resume handling code by generic helper. Almost no functional change, the only difference is in handling of hypothetical memory allocation failure on boot.
