Subject: [PATCH v2 4/5] genirq/msi: Engage the .msi_teardown() callback on domain removal
Date: Tue, 13 May 2025 17:31:43 +0100 [thread overview]
Message-ID: <20250513163144.2215824-5-maz@kernel.org> (raw)
In-Reply-To: <20250513163144.2215824-1-maz@kernel.org>
Kindly inform the MSI driver that we are tearing down the domain,
providing the allocation context previously populated on domain
creation.
