When CONFIG_KASAN is set, each call to ps8622_set() adds an object to the stack frame, leading to a warning about possible stack overflow: drivers/gpu/drm/bridge/parade-ps8622.c: In function 'ps8622_send_config': drivers/gpu/drm/bridge/parade-ps8622.c:338:1: error: the frame size of 5872 bytes is larger than 3072 bytes [-Werror=frame-larger-than=] Marking this as noinline_for_kasan completely avoids the problem.
