From 14b6d44d4720681a57b5d2c58cabdfc6364f8263 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 14 Mar 2016 10:00:42 +0100 Subject: Use scripts/clean-includes to drop redundant qemu/typedefs.h Re-run scripts/clean-includes to apply the previous commit's corrections and updates. Besides redundant qemu/typedefs.h, this only finds a redundant config-host.h include in ui/egl-helpers.c. No idea how that escaped the previous runs. Some manual whitespace trimming around dropped includes squashed in.
