From c276aca46d26aa2347320096f8ecdf5016795c14 Mon Sep 17 00:00:00 2001 From: vimal singh Date: Sat, 27 Jun 2009 11:07:06 +0530 Subject: [PATCH] mtd: nand: fix build failure and incorrect return from omap_wait() We need to include jiffies.h manually in some cases, and the status returned from omap_wait() was broken in two separate ways. Also add cond_resched() to the loop.
