Checkpatch indicated two problems with this function declaration:
1) The line ending with an open parenthesis, and
2) The following line - with the function parameters - has spaces in
its identation.

When I changed the line break to put the function name and its
parameter in the following line, both checkpath checks were eliminated.

So, the main change was the line break and, also, the line break (it)
removed the space in the following line.

Is it better to change the message and explain only about the line
break?

Thank you,
Aline
