[PATCH 00/22] mtd: nand: return error code of nand_scan(_ident, _tail) on error

[Masahiro Yamada]

nand_scan(), nand_scan_ident(), nand_scan_tail() return
an appropriate negative value on error.

Most of drivers return the value from them on error,
but some of them return the fixed error code -ENXIO
(and a few return -ENODEV).

This series make those drivers return more precise error code.
