From 8c24b85d2dd479558dc7a53be3f598007ec1a489 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Thu, 19 Dec 2019 23:21:52 +0100 Subject: [PATCH] thermal/drivers/of-thermal: Make of_thermal_destroy_zones static The function of_thermal_destroy_zones() is only used internally by the of_parse_thermal_zones() for rollbacking in case of error. Make it static and tag it as an __init function.
