From 15784862857c3c2214498defcfed84ff137fb81e Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 27 Nov 2006 17:22:19 +0100 Subject: [PATCH] [PATCH] nand_wait() timeout fixes Two fixes for the nand_wait() function in drivers/nand/nand_base.c: 1. Use correct timeouts. The original timeouts in Linux source are 400ms and 20ms not 40s and 20s 2. Return correct error value in case of timeout. 0 is interpreted as OK.
