mtd: nand: do not check R/B# for CMD_READID in nand_command(_lp)
Read ID (0x90) command does not toggle the R/B# pin. Without this patch, NAND_CMD_READID falls into the default: label, then R/B# is checked by chip->dev_ready(). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
