[Qemu-devel] [PATCH 02/22] uhci: Move checks to continue queuing to uhci_fill_queue() |
Date: |
Wed, 24 Oct 2012 18:13:58 +0200 |
Rather then having a special check to start queuing after the first packet,
and then another check for the other packets in uhci_fill_queue(), simply
check the previous packet beforehand in uhci_fill_queue()
