From 8a6036b92620a4ea0a1285d5c134ac9610ff4b32 Mon Sep 17 00:00:00 2001 From: Lan Tianyu Date: Wed, 14 Aug 2013 21:00:37 +0800 Subject: ACPI / thermal: Remove the unused lock of struct acpi_thermal The acpi_thermal->lock now just is initialized when a thermal zone device is added and destroyed when the thermal zone is removed. It is never used in any other places, so remove it. Signed-off-by: Lan Tianyu Acked-by: Zhang Rui Acked-by: Durgadoss R Signed-off-by: Rafael J.
