Subject: [PATCH v7 10/12] drm/xe: Move struct xe_ggtt to xe_ggtt.c
Date: Wed, 15 Oct 2025 09:47:19 +0200	[thread overview]
Message-ID: <20251015074708.1654014-24-dev@lankhorst.se> (raw)
In-Reply-To: <20251015074708.1654014-14-dev@lankhorst.se>

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

No users left outside of xe_ggtt.c, so we can make the struct private.

This prevents us from accidentally touching it before init.
