`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We need to prefer more robust and less ambiguous string interfaces. `obj_desc->(type|label)` are expected to be NUL-terminated strings as per "include/linux/fsl/mc.h +143" | ... | * struct fsl_mc_obj_desc - Object descriptor | * @type: Type of object: NULL terminated string | ... It seems `cmd_params->obj_type` is also expected to be a NUL-terminated string. A suitable replacement is `strscpy_pad` due to the fact that it guarantees NUL-termination on the destination buffer whilst keeping the NUL-padding behavior that `strncpy` provides. Padding may not strictly be necessary but let's opt to keep it as this ensures no functional change.
