I find if I build-in my framebuffer device driver, the logo can display.
But as a modules, even add export symbol fb_prepare_logo at fbmem.c, the build and load are ok,but the logo still can't display.
Anyway, thank you.

it is no longer exported as supposed to be used.
but the historical origin of the call may originate from patch:
