You can try the --smpl-spacing argument.  The original idea of that was
that people might like to put eg

+ if ( x )

Without the --smpl-spacing argument, Coccinelle would drop the spaces
around x.  With the argument, the code will be written as is.  But for
your case, it seems that --smpl-spacing also eliminates the reindentation
of function headers and function calls, when one of the
parameters/arguments changes.
