Subject: [patch V2 40/40] genirq/msi: Move msi_device_data to core
References: <20221121135653.208611233@linutronix.de>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Date:   Mon, 21 Nov 2022 15:40:18 +0100 (CET)
Precedence: bulk

Now that the platform MSI hack is gone, nothing needs to know about struct
msi_device_data outside of the core code.
