Subject: [PATCH 138/203] mtd: nand: pxa3xx: Replace host->page_size by
|
|
mtd->writesize
|
|
|
|
There's no need to privately store the device page size as it's
|
|
available in mtd structure field mtd->writesize.
|
|
Also, this removes the hardcoded page size value, leaving the
|
|
auto-detected value only.
