Subject: [PATCH net-next 01/27] can: janz-ican3: use sysfs_emit() in fwinfo_show()

From: Khaled Elnaggar <khaledelnaggarlinux@...il.com>

As recommended in Documentation/filesystems/sysfs.rst, show() callbacks
should use sysfs_emit() or sysfs_emit_at() to format values returned to
userspace. Replace scnprintf() with sysfs_emit() in fwinfo_show().
