strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. 'hw' is kzalloc'd just before this string assignment: | hw = kzalloc(sizeof(struct csio_hw), GFP_KERNEL); ... which means any NUL-padding is redundant. Since CSIO_DRV_VERSION is a small string literal (smaller than sizeof(dest)): ... there is functionally no change in this swap from strncpy() to strscpy(). Nonetheless, let's make the change for robustness' sake -- as it will ensure that drv_version is _always_ NUL-terminated.
