mtd: nand: remove unused and buggy get_platform_nandchip() helper function · 8142b47e

由 Boris BREZILLON 提交于 12月 14, 2015

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.

mtd: nand: kill the chip->flash_node field · 29574ede

由 Boris BREZILLON 提交于 12月 10, 2015

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().

mtd: nand: simplify nand_dt_init() usage · 7194a29a

由 Boris BREZILLON 提交于 12月 10, 2015

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.

mtd: nand: update mtd_to_nand() · 2d3b77ba

由 Boris BREZILLON 提交于 12月 10, 2015

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.
