drm/radeon/kms: fix bo's fence association
Previous code did associate fence to bo before the fence was emited and it also didn't lock protected access to ttm sync_obj member. Both of this flaw leads to possible race between different code path. This patch fix this by associating fence only once the fence is emitted and properly lock protect access to sync_obj member of ttm. Fix: https://bugs.freedesktop.org/show_bug.cgi?id=26438 and likely similar others bugs Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
