Subject: Smack - Fix build error with bringup unconfigured
X-Git-Tag: submit/tizen/20160405.082219~151
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f969e23de699010d43e3b084e7666a8c68099bb4;p=platform%2Fkernel%2Flinux-exynos.git

Smack - Fix build error with bringup unconfigured

The changes for mounting binary filesystems was allied
improperly, with the list of tokens being in an ifdef that
it shouldn't have been. Fix that, and a couple style issues
that were bothering me.
