[PATCH 52/70] cpufreq: interactive: fix show_target_loads and show_above_hispeed_delay

From: BÃlint Czobor
Date: Tue Oct 27 2015 - 13:33:27 EST


From: Minsung Kim <ms925.kim@xxxxxxxxxxx>

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).
