One patch per type of logical change is recommended, the location in the
file does not matter.

That's not a problem, and is not why your previous patches were
rejected.  Your previous patches were rejected as in your attempts to
fix coding style issues you added new ones.

Look at the examples on the staging mailing list for how to do this
well.  There are thousands of examples of "do only one type of change
per patch" out there.  To ignore the work others have done is odd.

Please start out by working in the drivers/staging/ part of the kernel
when learning how to do development, as that is explicitly what that
part of the kernel is for, and it keeps other maintainers from being
bothered by basic functionality and procedural issues like this.
