Subject: [PATCH v6 05/19] auxdisplay: img-ascii-lcd: Convert device attribute to sysfs_emit()
Date: Tue, 14 Sep 2021 16:38:21 +0200 [thread overview]
Message-ID: <20210914143835.511051-6-geert@linux-m68k.org> (raw)
In-Reply-To: <20210914143835.511051-1-geert@linux-m68k.org>
Convert the "message" device attribute from sprintf() to sysfs_emit(),
as the latter is aware of the PAGE_SIZE buffer.
Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
