From 52e895942ba065db563de042a4fff21fb38b26e6 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Fri, 24 Jul 2015 12:57:20 +0200 Subject: kdbus: fix sparse address-space annotation Make sure to properly annotate casts in 'struct iovec' if we cross address-spaces, to make sure sparse does not warn about them. All those conversions are fine, as we are allowed to pass those kvecs through the iovec importer.
