From 28ec8a864f4b67bb801aede7919391531612c7dd Mon Sep 17 00:00:00 2001 From: Boris BREZILLON Date: Tue, 20 Oct 2015 22:16:01 +0200 Subject: [PATCH] mtd: nand: sunxi: avoid retrieving data before ECC pass The in-band data are copied twice: before ECC correction and after the ECC engine has fixed all the fixable bitflips. Drop the useless memcpy_fromio operation by passing a NULL pointer when calling sunxi_nfc_read_buf().
