Subject: mtd: nand: set correct length to FBCR for a non-full-page write
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e32de766c2eb65f775438dd6d8ec5007619d2fe5;p=openwrt%2Fstaging%2Fblogic.git

mtd: nand: set correct length to FBCR for a non-full-page write

When we do a non-full-page write, the length be set to FBCR should
not be 'elbc_fcm_ctrl->index', it should be 'elbc_fcm_ctrl->index -
elbc_fcm_ctrl->column'.
