commit abd39c6ded9db53aa44c2540092bdd5fb6590fa8 upstream.
Observed crash in some scenarios when assertion has occurred, this is because hw structure is freed and is tried to get accessed in some functions where null check is already present. So, avoided the crash by making the hw to NULL after freeing.
