Coverity Issue: 323492 If the length of string pointed by 'name' is equal to or greater than the sizeof cptvf->dev_name string, the resultant string will not be null terminated. Using strlcpy would make sure the string would always be null terminated.
Fixes: 0dc1cffa4d33 ("crypto/octeontx: add hardware init routine") Coverity Issue: 323489 Fix null pointer dereferencing Fixes: bfe2ae495ee2 ("crypto/octeontx: add PMD skeleton") Coverity Issue: 323486 The function otx_cpt_get_resource() would be setting the pointer 'instance'. In case of error, 'instance' would be set to NULL, and returns rte_errno. If rte_errno when 'instance' is set to NULL, it can lead to NULL pointer dereferencing.
