Subject: drm/sched: Add device pointer to drm_gpu_scheduler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 8ab62eda177bc350f34fea4fcea23603b8184bfd
Patch-mainline: v5.18-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
Add device pointer so scheduler's printing can use
DRM_DEV_ERROR() instead, which makes life easier under multiple GPU
scenario.
v2: amend all calls of drm_sched_init()
v3: fill dev pointer for all drm_sched_init() calls
