Hi Karolina,
I think you are using redundant parentheses in "* (data ++)" but understand
that those increments and dereferences are equivalent to "* data ++"
(according to the C precedence rules).
Some time ago I suggested that you use those redundant parentheses because
Greg Kroah-Hartman had previously explained that he prefers not to see
"*foo++" because maintainers and reviewers are not required to remember the C
precedence rules.
I hope my suggestion isn't based on a misunderstanding of what Greg wants
here and that your patch can be accepted as is.
While we are at it, please notice that Maintainers of different subsystems
may see this topic from a different point of view and that they might very
well ask you for removing those redundant parentheses.
I'd suggest to use grep and find out what is preferred in other subsystems,
when you want to contribute to other parts of Linux.
Thanks,
Fabio
