Subject: [Filter/Custom/Easy] Add unregister function
X-Git-Tag: accepted/tizen/unified/20200629.143505~39
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9d3c0bcbccb7a245875268fec18db282ecb43bc7;p=platform%2Fupstream%2Fnnstreamer.git

[Filter/Custom/Easy] Add unregister function

This patch newly adds 'NNS_custom_easy_unregister()' function to remove
registered function so that pipeline itself can be reused without
changing custom model name.
