mtdinfo: fix `--all' for non-consecutive device numbers
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.
