	dee73c5 Browse files » UBI: simplify image sequence test ... The test: if (!a && b) a = b; can be symplified in: if (!a) a = b; And there's no need to test if ubi->image_seq is not null, because if it is, it is set to image_seq. So, we just test if image_seq is not null.

	2bae366 Browse files » UBI: fastmap: fix backward compatibility with image_seq ... Some old UBI implementations (e.g. U-Boot) have not implemented the image sequence feature. 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 `32bc482` and `2eadaad`) But fastmap scan functions (ubi_scan_fastmap() and scan_pool()) didn't. This patch fixes the issue.

	92924e7 Browse files » UBI: Fix PEB leak in wear_leveling_worker() ... get_peb_for_wl() removes the PEB from the free list. 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.
