If anyone has any objections, please let me know. ------------------ From: Ben Hutchings Commit 3e78080f8148 ('hwmon: (sht15) Check return value of regulator_enable()') depends on the use of devm_kmalloc() for automatic resource cleanup in the failure cases, which was introduced in 3.7. In older stable branches, explicit cleanup is needed.
