Subject: [PATCH 4.9 058/199] mtd: fix mtd_oobavail() incoherent returned value

From: Miquel Raynal <miquel.raynal@...tlin.com>

[ Upstream commit 4348433d8c0234f44adb6e12112e69343f50f0c5 ]

mtd_oobavail() returns either mtd->oovabail or mtd->oobsize. Both
values are unsigned 32-bit entities, so there is no reason to pretend
returning a signed one.
