4.9-stable review patch. If anyone has any objections, please let me know.

commit c176b10b025acee4dc8f2ab1cd64eb73b5ccef53 upstream.
The interrupt for the temperature threshold is not enabled at the end of the probe function, enable it after the setup is complete.
On the other side, the irq_enabled is not correctly set as we are checking if the interrupt is masked where 'yes' means irq_enabled=false.
irq_get_irqchip_state(data->irq, IRQCHIP_STATE_MASKED, &data->irq_enabled);
As we are always enabling the interrupt, it is pointless to check if the interrupt is masked or not, just set irq_enabled to 'true'.
