Ravishankar, you _really_ aren't looking too hard when
you do these changes.  Your error rate is _quite_ high.

All of these changes are in the same function and are
continuations of the initial printk.  Every one of these
after the first one should use KERN_CONT.

_Please_ look harder before submitting these changes.

Otherwise, I'm going to have to agree with Dan Carpenter.

I'm sure you can do these sorts of trivial changes, but
you absolutely _must_ lower your error rate, otherwise
you work will be ignored and you will lose whatever
reputation you might want to establish within this
community.

Best, Joe Perches
