[PATCH v2 3/7] mtd: nand: sunxi: make cur_off parameter optional in extra oob helpers

From: Boris Brezillon <hidden>
Date: 2016-03-30 15:39:50
Also in: linux-arm-kernel, linux-media, linux-spi
Subsystem: memory technology devices (mtd), nand flash subsystem, the rest · Maintainers: Miquel Raynal, Richard Weinberger, Vignesh Raghavendra, Linus Torvalds

Allow for NULL cur_offs values when the caller does not know where the
NAND page register pointer point to.
