From 7194e6f9c083e87171ddfc8b746f05e007f58132 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 24 Jul 2009 17:05:00 +0300 Subject: UBI: fix double free on error path If we fail in 'ubi_eba_init_scan()', we free 'ubi->volumes[i]->eba_tbl' in there, but also later free it in 'free_internal_volumes()'. Fix this by assigning NULL to 'ubi->volumes[i]->eba_tbl' after it is freed.
