Subject: [PATCH drm-next v5 06/14] drm/nouveau: get vmm via nouveau_cli_vmm()
Date:   Tue, 20 Jun 2023 02:42:09 +0200
Message-Id: <20230620004217.4700-7-dakr@redhat.com>
In-Reply-To: <20230620004217.4700-1-dakr@redhat.com>
References: <20230620004217.4700-1-dakr@redhat.com>

Provide a getter function for the client's current vmm context. Since
we'll add a new (u)vmm context for UMD bindings in subsequent commits,
this will keep the code clean.
