Subject: [PATCH 55/91] mtd: nand: embed an mtd_info structure into nand_chip
|
2016-03-22 21:14:51 +00:00
|
|
|
|
|
|
|
|
Currently all NAND controller drivers are providing both the mtd_info and
|
|
|
|
|
nand_chip struct and then let the NAND subsystem to initialize a few
|
|
|
|
|
things before registering the mtd instance to the MTD layer.
|
|
|
|
|
Embed an mtd_info field into nand_chip to add some consistency to all NAND
|
|
|
|
|
controller drivers.
|
|
|
|
|
This change will also help factorizing boilerplate code copied in all NAND
|
|
|
|
|
drivers.
