Hi Ying,

I assume that you are tweaking these pr_warning() lines
to beautify the output, but as far as source
code readability, I liked the previous syntax better.

Although maintainer's opinions vary, I generally do not
strictly enforce the 80 column rule for printk strings.
Ie. I think that code readability with good whitespace
indentation plus printk string grep-ability are more
important than strictly fitting within 80-columns.

thanks,
