i40iw: Replace the obsolete crypto hash interface with shash
This patch replaces the obsolete crypto hash interface with shash and resolves a build failure after merge of the rdma tree which is caused by the removal of crypto hash interface Removing CRYPTO_ALG_ASYNC from crypto_alloc_shash(), because it is by definition sync only Signed-off-by: Mustafa Ismail <mustafa.ismail@intel.com> Signed-off-by: Tatyana Nikolova <tatyana.e.nikolova@intel.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Doug Ledford <dledford@redhat.com>
