Replace the deprecated strncpy() with strscpy() for ib_name in
smc_pnet_add_ib(). The destination buffer should be NUL-terminated and
does not require any trailing NUL-padding. Since ib_name is a fixed-size
array, the two-argument form of strscpy() is sufficient and preferred.

I think d250f14f5f0754ce2d05d9c0ce778e4a51f488b0 has already done the
same thing.
