From 26d9be11485ea8c1102c3e8eaa7667412eef4950 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Thu, 28 Apr 2011 20:26:59 +0300 Subject: [PATCH] mtd: return badblockbits back In commit c7b28e25cb9beb943aead770ff14551b55fa8c79 the initialization of the backblockbits was accidentally removed. This patch returns it back, because otherwise some NAND drivers are broken.
