Subject: [PATCH 06/13] PCI: MSI: Kill msi_controller structure
Date: Thu, 25 Feb 2021 15:10:16 +0000 [thread overview]
Message-ID: <20210225151023.3642391-7-maz@kernel.org> (raw)
In-Reply-To: <20210225151023.3642391-1-maz@kernel.org>
msi_controller had a good, long life as the abstraction for
a driver providing MSIs to PCI devices. But it has been replaced
in all drivers by the more expressive generic MSI framework.
Farewell, struct msi_controller.
