Subject: [PATCH v2 3/7] base: Add calls to firewall controller
Date: Tue, 28 Jan 2020 16:38:02 +0100 [thread overview]
Message-ID: <20200128153806.7780-4-benjamin.gaignard@st.com> (raw)
In-Reply-To: <20200128153806.7780-1-benjamin.gaignard@st.com>
To avoid modifying all the drivers call firewall_set_default_config
before probe to apply the configuration define in device node (if any).
When unbinding the device try to apply configuration named "unbind".
