Staging tree's maintainer (Greg) disagrees with checkpatch.pl on this one
and prefers to keep these parentheses. So I would leave them be.

You can look up the staging mailing list for details.

Best regards,

Hi,

This is the friendly patch-bot of Greg Kroah-Hartman.  You have sent him
a patch that has triggered this response.  He used to manually respond
to these common problems, but in order to save his sanity (he kept
writing the same thing over and over, yet to different people), I was
created.  Hopefully you will not take offence and will fix the problem
in your patch and resubmit it so that it can be accepted into the Linux
kernel tree.

You are receiving this message because of the following common error(s)
as indicated below:

- You sent a patch that has been sent multiple times in the past, and is
  identical to ones that has been rejected.  Please always look at the
  mailing list traffic to determine if you are duplicating other
  people's work.

If you wish to discuss this problem further, or you have questions about
how to resolve this issue, please feel free to respond to this email and
Greg will reply once he has dug out from the pending patches received
from other developers.

thanks,

greg k-h's patch email bot
