From 0a3f3a1916bcac44a86ca89c874cdcad5e7746e9 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Thu, 7 Nov 2013 12:17:17 -0300 Subject: 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.
