From e542087701f09418702673631a908429feb3eae0 Mon Sep 17 00:00:00 2001 From: Pan Bian Date: Wed, 28 Nov 2018 11:20:03 +0800 Subject: ubi: Do not drop UBI device reference before using The UBI device reference is dropped but then the device is used as a parameter of ubi_err. The bug is introduced in changing ubi_err's behavior. The old ubi_err does not require a UBI device as its first parameter, but the new one does.
