From 66f5ce2538e06dd6d628e37bbd38c79631274c9f Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Wed, 23 Dec 2015 17:57:20 +0530 Subject: [PATCH] clk: qcom: common: check for failure We were not checking the return from devm_add_action() which can fail. Start using the helper and devm_add_action_or_reset() and return directly as we know that the cleanup has been done by this helper.
