crypto: qat - reduce size of mapped region
Restrict size of field to what is required by the operation. This issue was detected by smatch: drivers/crypto/qat/qat_common/qat_asym_algs.c:328 qat_dh_compute_value() error: dma_map_single_attrs() '&qat_req->in.dh.in.b' too small (8 vs 64) Signed-off-by: Adam Guerin <adam.guerin@intel.com> Reviewed-by: Giovanni Cabiddu <giovanni.cabiddu@intel.com> Signed-off-by: Giovanni Cabiddu <giovanni.cabiddu@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
