clang gets a bit confused by the code in the qed_mfw_process_tlv_req and ends up spilling registers to the stack hundreds of times. When sanitizers are enabled, this can end up blowing the stack warning limit: drivers/net/ethernet/qlogic/qed/qed_mng_tlv.c:1244:5: error: stack frame size (1824) exceeds limit (1280) in 'qed_mfw_process_tlv_req' [-Werror,-Wframe-larger-than] Apparently the problem is the complexity of qed_mfw_update_tlvs() after inlining, and marking the four main branches of that function as noinline_for_stack makes this problem completely go away, the stack usage goes down to 100 bytes.
