[PATCH v1 1/8] thermal: intel: intel_pch: Make pch_wpt_add_acpi_psv_trip() return int

[Rafael J. Wysocki]

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

Modify pch_wpt_add_acpi_psv_trip() to return an int value instead of
using a return pointer for that.

While at it, drop an excessive empty code line.
