ARM: S3C: Fix NAND device registration by s3c_nand_set_platdata().
Fix two bugs in s3c_nand_set_platdata() where thet device's platform data was not set, and the wrong error check was being performed on the return of s3c_nand_copy_set(). Fixes the following OOPS: Unable to handle kernel NULL pointer dereference at virtual address 00000004 PC is at s3c24xx_nand_probe+0x234/0x594 Signed-off-by: Ben Dooks <ben-linux@fluff.org>
