[RFC PATCH v2 0/6] UBI: Some cleanup and check if a vol exists when fastmap attaching

[Sheng Yong]

Hi, folks,

V2:
* change the commit message of PATCH 5. In normal cases, including unclean
  reboot and ECC scenario, there is no way to have two same vol_id saved in
  different slots in ubi->volumes[], so add_vol() in fastmap attach won't
  go wrong. Only if the on-flash fastmap is modified by hand, this issue
  may be triggered.
  Thanks Richard Weinberger for pointing this out.

* add two more cleanup.
  . add a helper function for updatting on-flash layout volumes. No
    semantic changes.

V1:

Thanks,
Sheng
