From ad9ca19aefe3f7b593ecae8255b7cf7207e32b95 Mon Sep 17 00:00:00 2001 From: Shmulik Ladkani Date: Sun, 10 Jun 2012 13:58:12 +0300 Subject: [PATCH] mtd: nand: Use the mirror BBT descriptor when reading its version commit 7bb9c75436212813b38700c34df4bbb6eb82debe upstream. The code responsible for reading the version of the mirror bbt was incorrectly using the descriptor of the main bbt. Pass the mirror bbt descriptor to 'scan_read_raw' when reading the version of the mirror bbt.
