Subject: [PATCH 2/8] rfkill: Improve code readability
Date: Tue, 19 Jan 2016 10:42:37 -0500 [thread overview]
Message-ID: <1453218163-31998-3-git-send-email-jprvita@endlessm.com> (raw)
In-Reply-To: <1453218163-31998-1-git-send-email-jprvita@endlessm.com>
RFKILL_BLOCK_SW value have just been saved to prev, no need to check it
again in the if expression. This makes code a little bit easier to read.
