mtd: rawnand: Stop passing mtd_info to drivers
|
expand
|
Hello, This is the first set of patches aiming at cleaning the raw NAND API. This one focuses on inconsistencies we have in the API + the nand_chip and nand_ecc_ctrl interfaces. Some functions/hooks are passed a nand_chip object, some are passed an mtd_info object and some are passed both. Since mtd_info can be extracted from nand_chip, we can simply always pass a nand_chip and make things consistent. Hopefully with these changes merged we'll stop seeing new drivers reproducing the same mistake (passing both mtd_info and nand_chip or using mtd_info where nand_chip is more appropriate). For those who want to see what's in the pipe, here is a branch [1] containing all the cleanups I plan to merge.
