In general, we don't take a patch just for white space without any
real need.  Please do a cleanup together with other real fix or
enhancement patches.

Also, the use of netdev_dbg() doesn't make sense here at all; the code
has nothing to do with the network.

Last but not least, you change the printk level by the conversion
silently.  It's really bad, please don't.  If you have to change the
printk level, give the convincing explanation.


thanks,

Takashi
