From: Boris BREZILLON Date: Tue, 20 Oct 2015 20:16:00 +0000 (+0200) Subject: mtd: nand: sunxi: fix sunxi_nfc_hw_ecc_read/write_chunk() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=74eb9ff54e21dbeefa04ff30e6aaf780b91dd261;p=openwrt%2Fstaging%2Fblogic.git mtd: nand: sunxi: fix sunxi_nfc_hw_ecc_read/write_chunk() The sunxi_nfc_hw_ecc_read/write_chunk() functions try to avoid changing the column address if unnecessary, but the logic to determine whether it's necessary or not is currently wrong: it adds the ecc->bytes value to the current offset where it should actually add ecc->size.
