For fun, I did a quick run of checkpatch.pl on the existing code.  
Here is what I get.

total: 364 errors, 1035 warnings, 814 checks, 12958 lines checked

Sounds to me like kind of a mess.  The bar was very low for initially
adding the driver, yet your process prevents any kind of cleanup in a
serious way.

Like I said, these white space issues could have been fixed in 10
seconds with a modern text editor if it was done before the initial
change.  But it sounds like now you are stuck with it.
