A number of functions in this file have large structures on the stack, ccp_run_aes_gcm_cmd() being the worst, in particular when KASAN is enabled on gcc: drivers/crypto/ccp/ccp-ops.c: In function 'ccp_run_sha_cmd': drivers/crypto/ccp/ccp-ops.c:1833:1: error: the frame size of 1136 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] drivers/crypto/ccp/ccp-ops.c: In function 'ccp_run_aes_gcm_cmd': drivers/crypto/ccp/ccp-ops.c:914:1: error: the frame size of 1632 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Avoid the issue by using dynamic memory allocation in the worst one of these.
