Subject: mtd: nand: sunxi: Remove unneeded ->cmdfunc(NAND_CMD_READ0, 0, page)
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=df5586d7bf6cce421ed48e9b2a88a8bdaa4fd9d0;p=linux.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.
