strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We know dev->name should be NUL-terminated based on the presence of a manual NUL-byte assignment. NUL-padding is not required as dev is already zero-allocated which renders any further NUL-byte assignments redundant: dev = pnp_alloc_dev(&pnpacpi_protocol, num, pnpid); ---> dev = kzalloc(sizeof(struct pnp_dev), GFP_KERNEL); Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. This simplifies the code and makes the intent/behavior more obvious.
