On some Lunar Lake pre-production systems, not all the MSI thermal vectors are valid. In that case instead of failing module load, continue with partial thermal interrupt support. pci_alloc_irq_vectors() can return less than expected maximum vectors. In that case call devm_request_threaded_irq() only for current maximum vectors.
