Subject: [PATCH 2/3] rt2x00: rt2800lib: use switch statement for RF specific setup
Date: Mon, 14 Oct 2013 21:59:51 +0200	[thread overview]
Message-ID: <1381780792-28894-2-git-send-email-juhosg@openwrt.org> (raw)
In-Reply-To: <1381780792-28894-1-git-send-email-juhosg@openwrt.org>

It is much more readable than multiple if-else-if
statements.
