Krzysztof Kozlowski 34e788045d thermal/drivers/broadcom: Fix race between removal and clock disable ... [ Upstream commit e90c369cc2 ] During the probe, driver enables clocks necessary to access registers (in get_temp()) and then registers thermal zone with managed-resources (devm) interface. Removal of device is not done in reversed order, because: 1. Clock will be disabled in driver remove() callback - thermal zone is still registered and accessible to users, 2. devm interface will unregister thermal zone. This leaves short window between (1) and (2) for accessing the get_temp() callback with disabled clock. Fix this by enabling clock also via devm-interface, so entire cleanup path will be in proper, reversed order.
