That's a good point. I wasn't sure if anybody was using it, but I can
remove it completely since no driver seems to be using the
thermal_generate_netlink_event() api.

$ git grep thermal_generate_netlink_event
Documentation/thermal/sysfs-api.rst:just need to call
thermal_generate_netlink_event() with two arguments viz
drivers/thermal/thermal_core.c:int
thermal_generate_netlink_event(struct thermal_zone_device *tz,
drivers/thermal/thermal_core.c:EXPORT_SYMBOL_GPL(thermal_generate_netlink_event);
include/linux/thermal.h:extern int
thermal_generate_netlink_event(struct thermal_zone_device *tz,
include/linux/thermal.h:static inline int
thermal_generate_netlink_event(struct thermal_zone_device *tz,
