Subject: [PATCH v2 1/4] thermal/of: Fix error code in of_thermal_zone_find()
Date: Tue, 9 Aug 2022 10:56:26 +0200 [thread overview]
Message-ID: <20220809085629.509116-1-daniel.lezcano@linaro.org> (raw)
From: Dan Carpenter <dan.carpenter@oracle.com>
Currently, if we cannot find the correct thermal zone then this error
path returns NULL and it would lead to an Oops in the caller. Return
ERR_PTR(-EINVAL) instead.
Fixes: 3bd52ac87347 ("thermal/of: Rework the thermal device tree initialization")
