It looks like this now violates the rule that function arguments should
appear just to the right of a (.  Maybe checkpatch didn't check this
because the line with the relevant argument is not affected by the change.

In version 2, I aligned the parameters with opening parentheses, but still
they appear on the left side in the patch. I double checked, parameters are
properly aligned in the code.
