From 5f28ecc1e909b2c3ab6ba4e9ba57c0f8dc66c30f Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Mon, 10 Oct 2022 16:03:11 +0100 Subject: [PATCH] thermal/drivers/tegra: Fix crash when getting critical temp Commit 13bea86623be ("thermal/of: Remove of_thermal_get_crit_temp()") removed the function of_thermal_get_crit_temp() and this is causing a NULL pointer deference crash when attempting to call the 'get_crit_temp' function pointer because this function pointer is no longer initialised. Fix this by replacing the call to the 'get_crit_temp' function pointer with a call to the function thermal_zone_get_crit_temp() instead.
