crypto: qat - use reference to structure in dma_map_single()
When mapping the input and output parameters, the implementations of RSA and DH pass to the function dma_map_single() a pointer to the first member of the structure they want to map instead of a pointer to the actual structure. This results in set of warnings reported by the static analyser Smatch: drivers/crypto/qat/qat_common/qat_asym_algs.c:335 qat_dh_compute_value() error: dma_map_single_attrs() '&qat_req->in.dh.in.b' too small (8 vs 64) drivers/crypto/qat/qat_common/qat_asym_algs.c:341 qat_dh_compute_value() error: dma_map_single_attrs() '&qat_req->out.dh.r' too small (8 vs 64) drivers/crypto/qat/qat_common/qat_asym_algs.c:732 qat_rsa_enc() error: dma_map_single_attrs() '&qat_req->in.rsa.enc.m' too small (8 vs 64) drivers/crypto/qat/qat_common/qat_asym_algs.c:738 qat_rsa_enc() error: dma_map_single_attrs() '&qat_req->out.rsa.enc.c' too small (8 vs 64) drivers/crypto/qat/qat_common/qat_asym_algs.c:878 qat_rsa_dec() error: dma_map_single_attrs() '&qat_req->in.rsa.dec.c' too small (8 vs 64) drivers/crypto/qat/qat_common/qat_asym_algs.c:884 qat_rsa_dec() error: dma_map_single_attrs() '&qat_req->out.rsa.dec.m' too small (8 vs 64) Where the address of the first element of a structure is used as an input for the function dma_map_single(), replace it with the address of the structure. This fix does not introduce any functional change as the addresses are the same.
