From 9d03280129e84f8cdfd83f84803a4548e3bf697d Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Wed, 10 Jan 2007 07:51:26 +0200 Subject: [MTD] OneNAND: Return an error if a read timeout occurs If OneNAND is operating within specification, all operations should easily be completed within the 20 millisecond timeout. This patch faithlessly adds a check for the timeout and returns an error in that case.
