From cf0fad49d17cb8273ce555dd5b7afab67d7923bf Mon Sep 17 00:00:00 2001 From: Minsung Kim Date: Sun, 25 Aug 2013 19:23:34 +0900 Subject: [PATCH] cpufreq: interactive: fix show_target_loads and show_above_hispeed_delay Remove a trailing whitespace from target_loads and above_hispeed_delay. Problem happens when user-space program tried to restore parameters that saved before changing parameters. In this case was returned error(EINVAL).
