Subject: [Intel-gfx] [PATCH 01/34] drm/i915/gvt: remove module refcounting in intel_gvt_{, un}register_hypervisor
Date: Mon, 11 Apr 2022 16:13:30 +0200 [thread overview]
Message-ID: <20220411141403.86980-2-hch@lst.de> (raw)
In-Reply-To: <20220411141403.86980-1-hch@lst.de>
THIS_MODULE always is reference when a symbol called by it is used, so
don't bother with the additional reference.
Signed-off-by: Christoph Hellwig <hch@lst.de>
