From 75bfa81bf0897ba87f1e1b9b576a07536029b86a Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Mon, 31 Oct 2016 00:38:21 +0200 Subject: [PATCH] virtio_ring: mark vring_dma_dev inline This inline function is unused on configurations where dma_map/unmap are empty macros. Make the function inline to avoid gcc errors because of an unused static function. Signed-off-by: Michael S.
