So, I tried right away and it was really as easy as expected:

=3D=3D=3D
@@
@@
- strlcpy
+ strscpy
  (...);
=3D=3D=3D

The ';' at the end ensures that spatch only looks for complete
statements not containing anything more than expressed.

I pushed out a branch for the testbots now:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/strlcpy

Patch granularity might not be perfect currently, but for testing this
should do.

All the best,
