Subject: [PATCH] mtd: drop unnecessary partition parser data
|
|
|
|
We should assign the MTD dev.of_node instead of the parser data field.
|
|
This gets us the equivalent partition parser behavior with fewer special
|
|
fields and parameter passing.
|
|
|
|
Also convert several of these to mtd_device_register(), since we don't
|
|
need the 2nd and 3rd parameters anymore.
