For comedi patches affecting a single driver, we prefer the driver name to be mentioned in the patch subject, like...

staging: comedi: cb_pcidas64: blah blah

For loop contains only an if conditional (and body of if conditional).
Conditional can be inverted and the loop continued if the new
conditional is true without modifying the program logic. This allows
one level of indentation to be removed.

Invert conditional and continue loop if new conditional evaluates to
true. Remove one level of indentation from subsequent loop body.

Since you are unindenting the code, you can reformat those function parameters at the same time to fix the multiline dereference.
