Hi Fuqian, Thank you for the pach.

Maybe "Several drivers cast a struct device pointer to a struct platform_device pointer only to then call platform_get_drvdata(). These constructs can be simplified by using dev_get_drvdata() directly." I would also replace the "gpu: " prefix with "drm: " in the subject line.
