X-Git-Tag: upstream/snapshot3+hdmi~5216^2~26
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b2273be8d2df7b77165a70930064aeb9e8faebfa;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

caif_virtio: Use vringh_notify_enable correctly

Check on the correct return value from
vringh_notify_enable_kern(). It returns false if
more packets are available, not true.
