Subject: [Qemu-devel] [PULL 5/9] xhci: rename xhci_complete_packet to xhci_try_complete_packet
Date: Mon, 6 Feb 2017 12:28:17 +0100 [thread overview]
Message-ID: <1486380501-13431-6-git-send-email-kraxel@redhat.com> (raw)
In-Reply-To: <1486380501-13431-1-git-send-email-kraxel@redhat.com>
Make clear that this isn't guaranteed to actually complete the transfer,
the usb packet can still be in flight after calling that function.
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
