[ Upstream commit a10549fcce2913be7dc581562ffd8ea35653853e ]
The commit 320406cb60b6 ("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.
