strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().

OK. It's always good to spell out in the change log whether it's a

Partially / too little (and no, I don't have an answer yet). I am
debugging a SERDES protocol change procedure from XFI to SGMII.

Hello Alexey,
No worries. I resolved the issue with Michael's help. The patch is
merged upstream and it fixes the issue.

In a COMPILE_TEST configuration, the cpm_uart driver uses symbols from
the cpm_uart_cpm2.c file. This file is compiled only when CONFIG_CPM2 is
set.
Without this dependency, the linker fails with some missing symbols for
COMPILE_TEST configuration that needs SERIAL_CPM without enabling CPM2.
