btw:

It's not possible to sed as the return value is different,
but here is a cocci script that converts strlcpy to strscpy
when the return value is unused.

@@
expression e1, e2, e3;
@@

- strlcpy(
+ strscpy(
e1, e2, e3);

This cocci script was used on sound/ awhile back.
see commit 75b1a8f9d62e.
