[PATCH 07/39] mtd: nand: denali: transfer OOB only when oob_required is set
From: Masahiro Yamada
Date: Sat Nov 26 2016 - 13:11:48 EST
Currently, the denali_read_page_raw() always transfers the OOB and
copy the data to chip->oob_poi, ignoring the oob_required argument.
Respect the oob_required argument.
