Subject: [PATCH 52/91] mtd: nand: add an mtd_to_nand() helper
|
2016-03-22 21:14:51 +00:00
|
|
|
|
|
|
|
|
Some drivers are retrieving the nand_chip pointer using the container_of
|
|
|
|
|
macro on a struct wrapping both the nand_chip and the mtd_info struct while
|
|
|
|
|
the standard way of retrieving this pointer is through mtd->priv.
|
|
|
|
|
Provide an helper to do that.
