From: Boris Brezillon Date: Mon, 15 May 2017 22:23:46 +0000 (+0200) Subject: mtd: nand: sunxi: Remove unneeded ->cmdfunc(NAND_CMD_READ0, 0, page) X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=df5586d7bf6cce421ed48e9b2a88a8bdaa4fd9d0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git mtd: nand: sunxi: Remove unneeded ->cmdfunc(NAND_CMD_READ0, 0, page) The core already sends the NAND_CMD_READ0 for us. Duplicating this call in the driver is useless and introduces a perf penalty.
