From f86787280b37e381f8d82f48583434d62dd16e27 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Thu, 16 Aug 2018 17:30:10 +0200 Subject: mtd: nand: Pass mode information to nand_page_io_req The NAND sub-layers are likely to need the MTD_OPS_XXX mode information in order to decide if they should enable/disable ECC or how they should place the OOB bytes in the provided OOB buffer. Add a field to nand_page_io_req to pass this information.
