Re: [PATCH v4 10/11] drm/amdgpu: job is secure iff CS is secure (v5)

Am 29.09.19 um 09:40 schrieb Huang, Ray:
Mark a job as secure, if and only if the command
submission flag has the secure flag set.

v2: fix the null job pointer while in vmid 0
submission.
v3: Context --> Command submission.
v4: filling cs parser with cs->in.flags
v5: move the job secure flag setting out of amdgpu_cs_submit()

At some point we need to cleanup struct amdgpu_job, but for now that is perfectly ok.
