Hi Sascha,

Fixed all the issues you mentioned.

All cases bail out:

barebox@Phytec phyCORE-i.MX35:/ ubiformat /dev/ram0
libmtd: error!: MEMGETINFO ioctl request failed
ubiformat: error!: cannot get information about "/dev/ram0"

barebox@Phytec phyCORE-i.MX35:/ ubiformat asdhkjh
libmtd: error!: cannot open "asdhkjh"
ubiformat: error!: cannot get information about "asdhkjh"

Will send an updated version rebase to 2012.12.0, soon.

Thanks,

   Wolfram
