Summary
In the Linux kernel, the following vulnerability has been resolved: net: stmmac: move the EST lock to struct stmmac_priv Reinitialize the whole EST structure would also reset the mutex lock which is embedded in the EST structure, and then trigger the following warning. To address this, move the lock to struct stmmac_priv. We also need to reacquire the mutex lock when doing this initialization.
