Subject: [PATCH 3/3] firewire: ohci: fix nonstandard build without debug
 facility

CONFIG_FIREWIRE_OHCI_DEBUG is currently a hidden kconfig variable, hence
is not going to be switched off by anybody.  Still, it can be switched
off but then compilation will fail in ohci_enable() at the expression
param_debug & OHCI_PARAM_DEBUG_BUSRESETS.
