From: Masahiro Yamada Date: Wed, 22 Mar 2017 20:07:24 +0000 (+0900) Subject: mtd: nand: denali: remove unnecessary writes to ECC_CORRECTION X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e713ddd87ccee801be1fd13f478407b1bde93c21;p=openwrt%2Fstaging%2Fblogic.git mtd: nand: denali: remove unnecessary writes to ECC_CORRECTION Because SUPPORT_15BITECC is defined, the following is dead code: #elif SUPPORT_8BITECC iowrite32(8, denali->flash_reg + ECC_CORRECTION); #endif Such ifdefs are useless and unacceptable coding style. These writes are not needed in the first place since ECC_CORRECTION is set up by the nand_init() function.
