Those in-line comments are there as a warning that these variables are special. 
Just because a tool such as checkpatch says to remove them does not mean that 
you should; however, if you want to get rid of the warnings, change the space(s) 
after the "*/" into a tab. That silences the checkpatch warning without removing 
the implicit warning that these variables are special.

NACK.

Keep in mind that when this driver was submitted, it ran checkpatch cleanly. The 
fact that there are now warnings is due to changes in the tool. Following those 
will be a never-ending task.
