From dc1f5988454d9dac8b9ba0c35266c8b4bc33ffa1 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Fri, 12 Sep 2014 18:55:26 +1000 Subject: [PATCH] ohci: Convert fprint/DPRINTF/print to traces This converts many kinds of debug prints to traces. This implements packets logging to avoid unnecessary calculations if usb_ohci_td_pkt_short/usb_ohci_td_pkt_long is not enabled. This makes OHCI errors (such as "DMA error") invisible by default.
