[PATCH] UBI: add ioctl compatibility

[Artem Bityutskiy <dedekind@infradead.org>]

Hi Arnd,

would you please glance if this patch all-right?



From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
Subject: [PATCH] UBI: add ioctl compatibility

UBI ioctl's do not work when running 64-bit kernel and 32-bit
user-land. Fix this by adding ioctl translation etries to
fs/compat_ioctl.c
