[PATCH linux-next] thermal: int340x: processor_thermal: Ack all PCI interrupts

From: Srinivas Pandruvada
Date: Wed Sep 20 2023 - 14:52:05 EST


All interrupts from the processor thermal PCI device requires ACK. This
is done by writing 0x01 at offset 0xDC in the config space. This is
already done for the thereshold interrupt. Extend this for the workload
hint interrupt.
