2019-02-05drm/amd/display: add gpio lock/unlockChiawen Huang1-0/+8
[Why] When querying HPD via GPIO flow, it will create a new gpio object then free in the end of query. There is a irql issue for HPD querying at ISR level. [How] Therefore, creating the HPD gpio object in dc_link and set it as unlcok in default. 1. reducing unnecessary malloc/free when HPD querying. 2. reducing init GPIO flow. 3. add lock/unlock to prevent multi gpio service running.
