6.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx> [ Upstream commit a8bbe6f10f78f85243ff821432c5d798a6d99ed4 ] Fold bind_cdev() into __thermal_cooling_device_register() and bind_tz() into thermal_zone_device_register_with_trips() to reduce code bloat and make it somewhat easier to follow the code flow. No intentional functional impact. Signed-off-by: Rafael J.
