The commit320406cb60("crypto: inside-secure - Replace generic aes with libaes") replaced crypto_alloc_cipher() with kmalloc(), but did not modify the handling of the return value. When kmalloc() returns NULL, PTR_ERR_OR_ZERO(NULL) returns 0, but in fact, the memory allocation has failed, and -ENOMEM should be returned.
