Use the macro 'swap()' defined in 'include/linux/minmax.h' to avoid
opencoding it.

I'm confused by the signed-off-by list. Are you Yang Guang and David is
your "English name"? If so then this is fine, but if you are different
people then everyone who handles the patch needs to add their own
signed-off-by.

Remove the curly {} braces as well because they are no longer required.

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:
- This looks like a new version of a previously submitted patch, but you
did not list below the --- line any changes from the previous version.
Please read the section entitled "The canonical patch format" in the
kernel file, Documentation/SubmittingPatches for what needs to be done
here to properly describe this.
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

Use the macro 'swap()' defined in 'include/linux/minmax.h' to avoid
opencoding it.
Changes from v1->v2:
- Delete the curly {} braces.
