kernel: backport cosmetic ubifs patch
Despite the MS_SILENT flag being set when probing for ubifs rootfs a logline indicating an error is generated during boot: UBIFS error (pid: 1): cannot open "ubi0:rootfs", error -19 This leads to confusion and there shouldn't be lines containing the word 'error' twice in a bootlog if actually everything is fine (just the rootfs happens to be something else than ubifs) The patch added has been submitted and was accepted upstream, see: http://lists.infradead.org/pipermail/linux-mtd/2016-June/068056.html http://patchwork.ozlabs.org/patch/637491 Signed-off-by: Daniel Golle <daniel@makrotopia.org>

+Subject: [PATCH] ubifs: silence error output if MS_SILENT is set
+X-Patchwork-Id: 637491
+X-Patchwork-Delegate: richard.weinberger@gmail.com
+To: linux-mtd@lists.infradead.org

+
+This change completes
+commit 90bea5a3f0bf680b87b90516f3c231997f4b8f3b
+which already implements support for MS_SILENT except for that one
+error message which is still being displayed despite MS_SILENT being
+set. Suppress that error message as well in case MS_SILENT is set.
