[PATCH v2 1/2] thermal: core: Change passive_delay and polling_delay data type

From: Rafael J. Wysocki
Date: Fri Jul 05 2024 - 15:46:51 EST


From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

It is better to use unsigned int as the data type for the passive_delay
and polling_delay arguments of thermal_zone_device_register_with_trips()
because they are implicitly cast to unsigned int anyway in
thermal_set_delay_jiffies() and if they happen to be negative at that
point, the resulting behavior may not be as desired.

Update the thermal_zone_device_register_with_trips() definition
accordingly.
