From f0fdaa4ad55b7c6e46a5ccb9102bc9a96cad360f Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Mon, 27 Oct 2025 21:04:09 -0700 Subject: [PATCH] virt: acrn: split acrn_mmio_dev_res out of acrn_mmiodev Add struct acrn_mmio_dev_res before struct acrn_mmio_dev. The former is used in the latter and breaking them up provides better kernel-doc documentation for the struct members.
