cover firewire: some simple kernel log changes

I wanted to hold off with posting the following few patches because I still want to add some firewire-core and firewire-net logging related updates as well. But since Carl may be interested in patch 2/3 right now, here they are.

1/3 firewire: do not expose globally unique IDs in the kernel log 2/3 firewire: ohci: use dev_printk API
3/3 firewire: sbp2: use dev_printk API

PATCH 1/3 firewire: do not expose globally unique IDs in the kernel log

Printing worldwide unique IDs in the kernel log is questionable from a privacy point of view. Some people edit such IDs out of the log before they post bug reports. Make life easier for them and do not log GUIDs anymore. For local debugging, GUIDs are still available during the lifetime of a device in /sys/bus/firewire/devices/fw*/guid.

Instead, log the vendor-unique part of the device ID (the OUI) in firewire-core and bus IDs in firewire-net.

Re: [PATCH 1/3] firewire: do not expose globally unique IDs in the kernel log

grumble.

I use those guids like so:

plug in dv cam, dmesg, cut guid to clipboard, run:
dvgrab -guid (paste)

It also kinda helps me keep track of what devices are misbehaving, but this alone isn't very important.

Any chance of making this configurable?

How about:

	#!/bin/sh
	guid=$(cat /sys/bus/firewire/devices/$1/guid)
	shift
	dvgrab -guid $guid "$@"

To be called as "dvgrab-wrapper fw3 [more dvgrab options]", with fw3 being the device of your choice, e.g. the one that just scrolled by in syslog.

Or you run "grep . /sys/bus/firewire/devices/*/guid | sed s/\\/guid:/\\t/" before dvgrab, and you get a list of GUIDs from which you can copy and paste.

Quoted 4 lines

It also kinda helps me keep track of what devices are misbehaving, but this alone isn't very important.

Any chance of making this configurable?

So far the configuration of the "new" firewire drivers were kept at an essential minimum, and I am hesitant to add more baroque ones. I would rather drop this patch now that there was negative feedback, unless there is going to be positive feedback as well.

I can't rely on these scripts being available, and I certainly won't to try and create them on the fly when I need them (which is often as a talk is starting and I am already in a panic trying to figure out why something isn't working... every second counts, and my brain is topped out.)

+1.

As a peace offering to people that want to x them out before posting:

To further describe my pain: I am going to run dmesg anyway to see if the device is being detected and or any errors. Once I see that it is connected, it is really nice having the guid right there.

I am really bummed I didn't invite you to PyCon in Leipzig so you
could see what I do first hand. Maybe next time.
