Subject: ubifs: remove useless code
X-Git-Url: https://git.sur5r.net/?p=u-boot;a=commitdiff_plain;h=5a08cfee3967d6e8174d7de135af1daa8e4aea00

ubifs: remove useless code

By checking ubifs source code, s_instances parameter is not
used anymore. So, set this parameter and the associated source
code under __UBOOT__ compilation.
