Subject: [PATCH 2/3] auxdisplay: charlcd: simplify init message display
Date: Fri,  1 Mar 2019 18:48:15 +0000	[thread overview]
Message-ID: <20190301184816.784-2-mans@mansr.com> (raw)
In-Reply-To: <20190301184816.784-1-mans@mansr.com>

If CONFIG_PANEL_CHANGE_MESSAGE is set, CONFIG_PANEL_BOOT_MESSAGE will
also be defined, so the double ifdef is pointless.  Simplify the code
further by using an intermediate macro rather duplicating most of the
line.
