Subject: auxdisplay: img-ascii-lcd: Convert device attribute to sysfs_emit()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=12a19324ebd9edc08edc0d7ff27a3662e1bb6e8c;p=linux.git

auxdisplay: img-ascii-lcd: Convert device attribute to sysfs_emit()

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