[ Upstream commit cbd8c5aae2a988bafd4586bea710eeddc30a82ce ]
There is a single IRQ handler for each LVTS thermal domain, and it is supposed to check each of its underlying controllers for the origin of the interrupt and clear its status. However due to a typo, only the first controller was ever being handled, which resulted in the interrupt never being cleared when it happened on the other controllers. Add the missing index so interrupts are handled for all controllers.
