Subject: virtio_ring: mark vring_dma_dev inline
X-Git-Url: http://git.cascardo.info/?p=cascardo%2Flinux.git;a=commitdiff_plain;h=75bfa81bf0897ba87f1e1b9b576a07536029b86a

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.
