Hmm, this is getting complicated... How about just add function to
drivers/video/omap/lcdc.c for something like omap_lcdc_get_status()
or similar?
Then you can define that function in some header as:
#if defined(CONFIG_ARCH_OMAP1) && defined(CONFIG_FB_OMAP)
extern int omap_lcdc_get_status(void);
#else
static inline int omap_lcdc_get_status(void)
{
return -ENODEV;
}
#endif
That way the defines can stay where they are and you don't need the
ugly ifdefs.

Tony
