From: Varka Bhadram <varkab@cdac.in>

This patch does the following changes
1. convert printk(KERN_DEBUG.. to netdev_dbg() if we have net_device object
   or convert to dev_dbg() if we have device object.
2. convert printk(KERN_WARNING.. to netdev_warn() if we have net_device object
   or convert to dev_warn() if we have device object
3. convert printk() to pr_*

This changes output from a compact form to
usig very many individual lines like:

<7>dev->name: reg[addr]: p1 p2 p3 p4 p5 p6 p7 p8
<7>dev->name: reg[addr]: p9 pa ...            pn

to:

<7>bus desc/dev->name: reg[addr]:
<7> p1
<7> p2
...
<7>bus desc/dev->name: reg[addr]:
<7> p9
<7> pa
...
<7> pn

You mean to say that the pr_debug will insert the new line ?... I dont think so..


I think this patch will do the job as you show like

<7>dev->name: reg[addr]: p1 p2 p3 p4 p5 p6 p7 p8
<7>dev->name: reg[addr]: p9 pa ...            pn

Try it.

If you're using dynamic_debug, remember to
enable all the lines.

You'll have to buffer the line locally because
there's no simple way to use dynamic debug with
line continuations.

I think you should buffer the lines locally.

btw; It seems what you submitted is a partial revert and
so it should be described as such in the patch description.
