Subject: [PATCH 04/13] PCI: hyperv: Drop msi_controller structure
Date: Thu, 25 Feb 2021 15:10:14 +0000
Message-ID: <20210225151023.3642391-5-maz@kernel.org> (raw)
In-Reply-To: <20210225151023.3642391-1-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.
