From 5df3c2b62cebaa0ddb2817364f93726e5dbe3525 Mon Sep 17 00:00:00 2001 From: Sandeep Paulraj Date: Sat, 7 Nov 2009 14:25:18 -0500 Subject: [PATCH] NAND: Don't walk past end of oobfree[] When computing oobavail from the list of free areas in the OOB, don't assume there will always be an unused slot at the end. This syncs up with the kernel NAND driver.
