4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Weinberger richard@nod.at
commit 08acbdd6fd736b90f8d725da5a0de4de2dd6de62 upstream.
This reverts commit 353748a359f1821ee934afc579cf04572406b420. It bypassed the linux-mtd review process and fixes the issue not as it should.
