From 8136508cd6075a74e68a8d1cde8399a558ca27a7 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Sun, 27 Apr 2008 01:51:12 +0900 Subject: [PATCH] [MTD] [NAND] at91_nand: use at91_nand_{en,dis}able consistently. Use at91_nand_enable(), at91_nand_disable() to manipulate enable_pin. No functional changes.
