Hello Güngör,
You have a typo in the subject for this patch.
"ssv_snp" should be "ssv_dnp"

Where possible, fixes like this should use the dev_printk versions.
For instance, this one would be:
dev_info(dev->class_dev, "dnp:");
But, there is a cleaner fix for this file. See below.

There are only two printk's in this file, both in the "attach" routine.
The first one does not have a "\n" and the function could exit without
ever terminating the message.
A better fix would be to merge the two messages into one "attached" message
at the end of the function. You could also use the dev->board_name instead of
the open coded string. Something like:
dev_info(dev->class_dev, "%s: attached\n", dev->board_name);
Also, the message should be moved so that it's the last thing that happens
before the function returns.

Hartley
