Subject: [RFC PATCH v3 06/12] firmware: arm_scmi: Add is_scmi_protocol_device()
Date: Tue, 11 May 2021 02:20:34 +0200	[thread overview]
Message-ID: <20210511002040.802226-7-peter.hilber@opensynergy.com> (raw)
In-Reply-To: <20210511002040.802226-1-peter.hilber@opensynergy.com>

The scmi-virtio transport driver will need to distinguish SCMI protocol
devices from the SCMI instance device in the chan_setup() and
chan_free() ops. Add this internal helper to be able to distinguish the
two.
