Masahiro Yamada f0dbe4aa35 mtd: nand: mediatek: return error code of nand_scan_ident/tail() on error 
The nand_scan_ident/tail() returns an appropriate error value when
it fails.  Use it instead of the fixed error code -ENODEV.

RogerCC Lin 559e58e7ed mtd: nand: fix chances to create incomplete ECC data when writing 
When mtk_nfc_do_write_page() comparing the sector number,because the
sector number field is at the 12th-bit position of NFI_BYTELEN
register,the masked register should be shifted 12 bits before being
compared.The result of this bug may cause the second subpage has
incomplete ECC parity bytes.
