[Qemu-devel] [PATCH 01/32] ehci: Add a ehci_writeback_async_complete_packet helper function |

From: Hans de Goede <address@hidden>
Also drop the warning printf, which was there mainly because this was an
untested code path (as the previous bug fixes to it show), but that no
longer is the case now :)
