If anyone has any objections, please let me know. ------------------ From: Chenyuan Yang [ Upstream commit 2542a3f70e563a9e70e7ded314286535a3321bdb ] Not all devices have an ACPI companion fwnode, so adev might be NULL. This is similar to the commit cd2fd6eab480 ("platform/x86: int3472: Check for adev == NULL"). Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in int3402_thermal_probe(). Note, under the same directory, int3400_thermal_probe() has such a check.
