Patch-mainline: v5.13-rc1
Subject: PCI: hv: Drop msi_controller structure
Git-commit: e0fad163b6e7482be32ae99662240268aa0e1bf1
References: bsc#1204446
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.
