ARM: S3C24XX: fix s3c2410fb platdata passing
Setting s3c2410fb_mach_info displays field with a struct marked as __initdata means it won't be available later for ioctls like FBIOPUT_VSCREENINFO and they will fail. Copying in s3c24xx_fb_set_platdata() is fixing this issue. Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
