[FFmpeg-devel] [PATCH 08/10] avfilter/dnn_backend_tf: check TF_OperationOutputType return value

[Zhao Zhili <quinkblack@foxmail.com>]

From: Zhao Zhili <zhilizhao@tencent.com>

This also fixed a warning: implicit conversion from enumeration
type 'TF_DataType' (aka 'enum TF_DataType') to different
enumeration type 'DNNDataType'.
