nuc900fb_map_video_memory is called by an devinit function that may be called at run-time, but the function itself is marked __init and will be discarded after boot. To avoid calling into a function that may have been overwritten, mark nuc900fb_map_video_memory itself as __devinit. Without this patch, building nuc950_defconfig results in: WARNING: drivers/video/built-in.o(.devinit.text+0x26c): Section mismatch in reference from the function nuc900fb_probe() to the function .init.text:nuc900fb_map_video_memory() The function __devinit nuc900fb_probe() references a function __init nuc900fb_map_video_memory(). If nuc900fb_map_video_memory is only used by nuc900fb_probe then annotate nuc900fb_map_video_memory with a matching annotation.
