[PATCH net v2 0/4] net: dsa: realtek: use devm_mutex_init

[Luiz Angelo Daros de Luca]

This series fixes mutex teardown in the Realtek DSA drivers.

With CONFIG_DEBUG_MUTEXES enabled, mutex_destroy() must be called before
the mutex is discarded. Using devm_mutex_init() lets the driver core
handle that automatically.

The changes are split into individual commits based on the feature that
introduced each lock to allow proper backports to stable trees.
