Subject: [PATCH v1 6/6] thermal: intel: int340x: Drop pointless cast to unsigned long

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

The explicit casting from int to unsigned long in
int340x_thermal_get_zone_temp() is pointless, becuase the multiplication
result is cast back to int by the assignment in the same statement, so
drop it.

No expected functional impact.
