Subject[PATCH 4.4 106/107] ubi: Fix Fastmaps update_vol()
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Richard Weinberger <richard@nod.at>

commit f7d11b33d4e8cedf19367c09b891bbc705163976 upstream.

Usually Fastmap is free to consider every PEB in one of the pools
as newer than the existing PEB. Since PEBs in a pool are by definition
newer than everything else.
But update_vol() missed the case that a pool can contain more than
one candidate.
