crypto: sun4i-ss - Always use sun4i_tfm_ctx for storing pointer to dev ss
The dev *ss is stored both in sun4i_tfm_ctx and sun4i_req_ctx. Since this pointer will never be changed during tfm life, it is better to remove it from sun4i_req_ctx. Signed-off-by: LABBE Corentin <clabbe.montjoie@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
