[PATCH] thermal/drivers/rcar: add error checking in probe()
From: Dan Carpenter
Date: Tue Jun 23 2026 - 03:50:31 EST
The thermal_zone_device_register_with_trips() can fail for a number of
reasons, including allocation failures. Check for error pointers to
avoid an error pointer dereference.
Fixes: 9d617949d490 ("thermal/drivers/renesas: Group all renesas thermal drivers together")
