My script makes a best effort attempt to group changes by file.  It
takes the first warning presented by the compiler then greps the
output for all issues pertaining to that file.  I then split the patch
by issue (i.e. different patches for; kernel-doc, unused variables,
bracketing etc).

One issue you might be seeing is the potential for one fixed issue to
cause another i.e. when one unused variable is removed which was the
only user of another, leading to a subsequent fix of the newly unused
variable.

Other than that, I'm not sure why they would end up out of order.
