[ralf@linux-mips.org: But which is not strictly a MIPS32 compliant device which also is why it identifies itself with the Legacy Vendor ID in the PrID register. When applying the patch I shoveled some code around to keep things in alphabetical order and avoid forward declarations.] Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

So, when erase blocks are written, the image sequence in the ec header is lost (set to zero). UBI scan_all() takes this case into account (commits 32bc4820287a1a03982979515949e8ea56eac641 and 2eadaad67b2b6bd132eda105128d2d466298b8e3) But fastmap scan functions (ubi_scan_fastmap() and scan_pool()) didn't.

If the WL subsystem detects that no wear leveling is needed it cancels the operation and drops the gained PEB. In this case we have to put the PEB back into the free list.
