Subject: [PATCH v2 10/18] auxdisplay: ht16k33: Use HT16K33_FB_SIZE in ht16k33_initialize()
Date: Fri, 25 Jun 2021 14:58:54 +0200 [thread overview]
Message-ID: <20210625125902.1162428-11-geert@linux-m68k.org> (raw)
In-Reply-To: <20210625125902.1162428-1-geert@linux-m68k.org>
Use the existing HT16K33_FB_SIZE definition instead of open-coding the
same calculation using an hardcoded value.
While at it, restore reverse Christmas tree variable declaration order.
