it's good to reflect in docs that sysfs_emit_at/sysfs_emit_pos is
only for "legacy" code and should not be used in new code (checkpatch.pl
warning?)
because of sysfs design principles.
And something about newlines "General rule is to add newlines at the end of
output."
Thanks,
Denis
t sure about existing cases, but I think it's a good
checkpatch.pl warning for new patches. It should be
possible to check sysfs_emit() calls.
Thanks,
Denis
