Subject: fusion-util: geomagnetic-field: Remove unused functions
X-Git-Tag: accepted/tizen/unified/20230831.081039~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F58%2F297958%2F1;p=platform%2Fcore%2Fapi%2Fsensor.git

fusion-util: geomagnetic-field: Remove unused functions

Functions below are not used and not tested by the UTC.
 - fusion-util.c: clamp, matrixToQuat
 - geomagnetic-field.c: getDeclination, getInclination

Thus, they are removed.
