crypto: cryptd - Fix skcipher instance memory leak
cryptd_skcipher_free() fails to free the struct skcipher_instance allocated in cryptd_create_skcipher(), leading to a memory leak. This is detected by kmemleak on bootup on ARM64 platforms: unreferenced object 0xffff80003377b180 (size 1024): comm "cryptomgr_probe", pid 822, jiffies 4294894830 (age 52.760s) backtrace: kmem_cache_alloc_trace+0x270/0x2d0 cryptd_create+0x990/0x124c cryptomgr_probe+0x5c/0x1e8 kthread+0x258/0x318 ret_from_fork+0x10/0x1c Fixes: 4e0958d19bd8 ("crypto: cryptd - Add support for skcipher") Cc: <stable@vger.kernel.org> Signed-off-by: Vincent Whitchurch <vincent.whitchurch@axis.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
