2015-12-18mtd: nand: remove unused and buggy get_platform_nandchip() helper functionBoris BREZILLON2-10/+0
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.

2015-12-18mtd: nand: kill the chip->flash_node fieldBoris BREZILLON2-8/+2
Now that the nand_chip struct directly embeds an mtd_info struct we can get rid of the ->flash_node field and forward set/get_flash_node requests to the MTD layer. As a side effect, we no longer need the mtd_set_of_node() call done in nand_dt_init().

2015-12-18mtd: nand: simplify nand_dt_init() usageBoris BREZILLON1-10/+11
nand_dt_init() function requires 3 arguments where it actually needs one (dn and mtd can both be retrieved from chip). Drop these parameters. Testing for dn != NULL inside nand_dt_init() also helps simplifying the caller code.

2015-12-18staging: mt29f_spinand: remove useless mtd->priv = chip assignmentBoris BREZILLON1-1/+0
mtd_to_nand() now uses the container_of() approach to transform an mtd_info pointer into a nand_chip one. Drop useless mtd->priv assignments from NAND controller drivers. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

2015-12-18mtd: nand: update mtd_to_nand()Boris BREZILLON1-1/+1
Now that all drivers are using the mtd instance embedded in the nand_chip struct we can safely update the mtd_to_nand() implementation to use the container_of macro instead of returning the content of mtd->priv. This will allow us to remove mtd->priv = chip assignments done in all NAND controller drivers.
