Subject[PATCH v3 6/6] thermal: brcmstb_thermal: Register different ops per process
Date
Since we do not have interrupts on BCM7216, we cannot have trip point
crossing, the thermal subsystem expects us to provide a NULL set_trips
operation in that case, so make it possible to provide per-process
thermal_zone_of_device_ops
