mtd: nand: omap: cleanup: replace local references with generic framework names
This patch updates following in omap_nand_probe() and omap_nand_remove() - replaces "info->nand" with "nand_chip" (struct nand_chip *nand_chip) - replaces "info->mtd" with "mtd" (struct mtd_info *mtd) - white-space and formatting cleanup Signed-off-by: Pekon Gupta <pekon@ti.com> Tested-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
