From edeee341fd6c1099de357c517af215bee2c6f766 Mon Sep 17 00:00:00 2001 From: Leonid Maksymchuk Date: Wed, 4 Mar 2020 13:38:11 +0200 Subject: [PATCH] platform/x86: asus_wmi: Fix return value of fan_boost_mode_store Function fan_boost_mode_store returns 0 if store is successful, this leads to infinite loop after any write to it's sysfs entry: # echo 0 >/sys/devices/platform/asus-nb-wmi/fan_boost_mode This command never ends, one CPU core is at 100% utilization. This patch fixes this by returning size of written data.
