| |
UBI assumes that ubi_attach_info will only contain ubi_ainf_volume structures for volumes with at least one LEB. In scanning mode this is true because UBI can nicely create a ubi_ainf_volume on demand while creating the EBA table.
For fastmap this is not true, the fastmap on-flash structure has a list of all volumes, the ubi_ainf_volume structures are created from this list. So it can happen that an empty volume ends up in init_volumes().
We can easely deal with that by looking into ->leb_count too.
