Subject: [PATCH v2 06/15] PCI: hv: Drop msi_controller structure
Date: Mon, 22 Mar 2021 18:46:05 +0000	[thread overview]
Message-ID: <20210322184614.802565-7-maz@kernel.org> (raw)
In-Reply-To: <20210322184614.802565-1-maz@kernel.org>

The Hyper-V PCI driver still makes use of a msi_controller structure,
but it looks more like a distant leftover than anything actually
useful, since it is initialised to 0 and never used for anything.

Just remove it.
