From 18f95a3640dbf421ab9532e517070a0c1cd4d582 Mon Sep 17 00:00:00 2001 From: Lorenzo Pieralisi Date: Wed, 15 Oct 2014 18:29:54 +0100 Subject: [PATCH] drivers: cpuidle: Remove cpuidle-arm64 duplicate error messages Current CPUidle driver for arm64 machines spits errors upon idle state initialization and cpuidle driver registration failures. These error messages are already printed in core code so there is no need to print them again. This patch removes the duplicate print messages from the cpuidle-arm64 driver.
