Subject: drm/amdgpu: revert "fix limiting AV1 to the first instance on VCN3"
 v3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Git-commit: d4423feeb7d316f1a31a5865a21b195940d4d7e9
Patch-mainline: v6.1-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849

This reverts commit 250195ff744f260c169f5427422b6f39c58cb883.

The job should now be initialized when we reach the parser functions.

v2: merge improved application check into this patch
v3: back to the original test, but use the right ring
