X-Git-Tag: submit/tizen/20200423.063253~27
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9dd10c4c8b49fdcb3b978e121197ef3ef7a91acd;p=platform%2Fcore%2Fmultimedia%2Finference-engine-interface.git

Rename hanel to mBackendModule

Just for the cleanup, rename handler to mBackendModule.
The handle points to backend library loaded by dlsym function.
