Subject: Fix qualifiers on aux functions for solveLP()
X-Git-Tag: submit/tizen_ivi/20141117.190038~2^2~985^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fe6a7e935db6c2f1cf669d0a0e5c0e73a4a1d8ab;p=profile%2Fivi%2Fopencv.git

Fix qualifiers on aux functions for solveLP()

Change qualifiers on auxiliary functions (for solveLP() procedure) from
const (that does not have much sense) to static (that makes them
invisible for outside world and hopefully exacerbates optimization).
