Subject: [PATCH v3 06/14] PCI: hv: Drop msi_controller structure

From: Marc Zyngier <[email-masked]>
Date: Tue, 30 Mar 2021 16:11:37 +0100

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.
