Hmm, didn't CC Brian Foster. Must have mixed up my headers...

When we have assigned non-consecutive device numbers to our MTD devices, then we run `mtdinfo --all', we get errors once mtdinfo tries to process the devices in the "hole". For instance, suppose that at boot time, we have one MTD (/dev/mtd0) then perform a sequence like the following: # modprobe mtdram # modprobe nandsim # rmmod mtdram Then at this point, we have should have devices 0 and 2 without 1. Then: # mtdinfo --all ... mtdinfo: error!: mtd1 does not correspond to any existing MTD device We add a check to first see if device is present, then continue to the next ID if it doesn't exist.
