Hey,
You forgot to add these commits to linux-next:
drm: Move struct drm_device.pdev to legacy
https://patchwork.kernel.org/project/intel-gfx/cover/20210107080748.4768-1-t...
I committed these patches to my local tree and that solved my problem.
- v3,4/8] drm/i915: Remove references to struct drm_device.pdev https://patchwork.kernel.org/project/intel-gfx/patch/20210107080748.4768-5-tzimmermann@suse.de/
- [v3,5/8] drm/i915/gt: Remove references to struct drm_device.pdev https://patchwork.kernel.org/project/intel-gfx/patch/20210107080748.4768-6-tzimmermann@suse.de/
- [v3,6/8] drm/i915/gvt: Remove references to struct drm_device.pdev https://patchwork.kernel.org/project/intel-gfx/patch/20210107080748.4768-7-tzimmermann@suse.de/
- [v3,8/8] drm: Upcast struct drm_device.dev to struct pci_device; replace pdev https://patchwork.kernel.org/project/intel-gfx/patch/20210107080748.4768-9-tzimmermann@suse.de/
These patches have not been merged yet as they have to wait for some preparation in the i915 driver.
I reduced the final patch, so it should change the buggy code. Could you please apply only the attached patchfile and report if it fixes the issue?
Best regards Thomas
Thanks to all!
