From 8142b47ef33c655a34e08efd46b65732fe190675 Mon Sep 17 00:00:00 2001 From: Boris BREZILLON Date: Mon, 14 Dec 2015 16:13:31 +0100 Subject: mtd: nand: remove unused and buggy get_platform_nandchip() helper function Nobody uses the get_platform_nandchip() helper function which is supposed to return a pointer to a platform_nand_chip struct from an mtd_info pointer. Moreover, this function is buggy since the introduction of the plat_nand layer (chip->priv is now storing a pointer to an intermediate plat_nand_data structure allocated in plat_nand_probe(), and we have no way to retrieve a pointer to the provided platform_nand_chip struct from this plat_nand_data pointer). While we are at it, remove the useless (and buggy, since it's pointing to something stored on the stack) data->chip.priv assignment.
