Subject: [PATCH] mtd: fix mtd_oobavail() incoherent returned value
Git-commit: 4348433d8c0234f44adb6e12112e69343f50f0c5
Patch-mainline: v5.0-rc1
References: bsc#1051510

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.
