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
