Subject: [PATCH v5 05/19] auxdisplay: img-ascii-lcd: Convert device attribute to sysfs_emit()
Date: Wed, 11 Aug 2021 11:57:45 +0200	[thread overview]
Message-ID: <20210811095759.1281480-6-geert@linux-m68k.org> (raw)
In-Reply-To: <20210811095759.1281480-1-geert@linux-m68k.org>

Convert the "message" device attribute from sprintf() to sysfs_emit(),
as the latter is aware of the PAGE_SIZE buffer.
