UBI Fastmap is an optional feature which stores the physical to
logical eraseblock relations in a checkpoint (called fastmap) to
reduce the initialization time of UBI. The current init time of UBI
is proportional to the number of physical erase blocks on the FLASH
device. With fastmap enabled the scan time is limited to a fixed
number of blocks.

Aiaiai complains and linux-next build fails :-( Last time I forgot to
enable the fastmap kbuild option so aiaiai checked with that option
disabled. Now I enabled it with a simple hack (default n -> default y)
and here are aiaiai's complaints - there is a build failure for
ARCH=i386.

Build fix for linux-next is on the way into your inbox.
I'm currently looking at the aiaiai output.

OK, I see, goto out is missing after line 919. Please, send a short fix
- I'll squash it in. But general error-path rework is needed for this
function, may be separately.


Yeah, it looks like all issues reported by aiaiai are caused by the missing goto.
Can you deal with the patch below or do you want me to send it using git send-email?

Thanks,
