From d8d94ba3fc4d28753d0d6ba08340d8467380e666 Mon Sep 17 00:00:00 2001 From: Changbin Du Date: Tue, 6 Jun 2017 15:56:10 +0800 Subject: [PATCH] drm/i915/gvt: Cleanup struct intel_gvt_mmio_info The size, length, addr_mask fields actually are not necessary. Every tracked mmio has DWORD size, and addr_mask is a legacy field.
