Subject: [PATCH v2 1/4] thermal/of: Fix error code in of_thermal_zone_find()

From: Dan Carpenter <dan.carpenter@...cle.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")
