[ 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.
