Subject: [PATCH 2/3] auxdisplay: charlcd: use null character instead of zero literal to terminate strings
Date: Sat, 10 Feb 2018 00:50:11 +0100 [thread overview]
Message-ID: <20180209235012.4993-3-rabel@robertabel.eu> (raw)
In-Reply-To: <20180209235012.4993-2-rabel@robertabel.eu>
Using '\0' instead of plain 0 makes the intent clearer that this is indeed a string and not a series of integers.
