Miller" Add function helper, fb_is_primary_device(). Given struct fb_info, it will return a nonzero value if the device is the primary display. Currently, only the i386 is supported where the function checks for the IORESOURCE_ROM_SHADOW flag. Signed-off-by: Antonino Daplas --- Geert Uytterhoeven wrote: > On Sun, 27 May 2007, Antonino A.
