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-tzimmermann@xxxxxxx/
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@xxxxxxx/>
* [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@xxxxxxx/>
* [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@xxxxxxx/>
* [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@xxxxxxx/>
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!
