Subject: Re: [PATCH] drm/radeon: remove load callback
Dear Thomas,
Thank you for testing my patch. The dev->dev_private is indeed the problem.
However, most of the functions that uses dev->dev_private is passing
drm_device as parameter, and then uses dev->dev_private to retrieve
radeon_device,
contradicting what the patch intended. It should use radeon_device directly.
Should I send a follow up patch with the updated patch?
Thank you.
Best Regards
Wu
