[PATCH v1] thermal: intel: int340x: Fix unitialized variable error
From: Rafael J. Wysocki
Date: Tue Jan 24 2023 - 11:38:58 EST
From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
If PATC evaluation fails in int340x_thermal_zone_add(), trip_cnt will
not be initialized when allocating the trips array later.
Address this by initializing trip_cnt to 0.
While at it, move the status variable definition lower for better
code readability.
Fixes: d58c653e9e26 ("thermal: intel: int340x: Use generic trip points")
