- use release instead of free for the fence destroy identifier - nvhost_dev is a struct name, so use nvhost_device - compare nvgpu_nvhost_syncpt_read_ext_check retval properly Also, if the syncpt read fails when checking for fence expiration, behave as if the wait isn't expired. Possibly getting stuck is safer than possibly continuing too early.
