Subject: [PATCH] tty: vt: replace _manual_ swap with swap macro in set_selection
Date: Fri, 10 Nov 2017 16:05:45 -0600	[thread overview]
Message-ID: <20171110220545.GA28610@embeddedor.com> (raw)

Make use of the swap macro instead of _manually_ swapping values
and remove unnecessary variable tmp.

This makes the code easier to read and maintain.

This code was detected with the help of Coccinelle.
