From 8c797e758ad41b8dd6ea6f72c6f0194dedb30a2f Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Thu, 12 Jan 2017 23:26:22 +0200 Subject: virtio-ccw: fix ring sizing Current code seems to assume ring size is always decreased but this is not required by spec: what spec says is just that size can not exceed the maximum. Fix it up. Signed-off-by: Michael S.
