typecheck creates local variables based on the type passed. That could result in stack frame size warnings like below in certain configs:
drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu13/smu_v13_0_6_ppt.c:2885:1: error: the frame size of 8304 bytes is larger than 2048 bytes [-Werror=frame-larger-than=] Checking against the pointer type is sufficient for the purpose of getting a diagnostic message during build time.
