As far as i can see the patch is spot on, thanks for that.

Can you split this in three since it covers 3 separate drivers.
For each one you can get a smaller CC list - patches with 20+ people
tend to get blocked :-(

We can pick the PANFROST entries from the get_maintainer.pl output,
and add them to the commit message.
Thus git send-email will parse the commit message and automatically CC
the people ;-)

Hi Fuqian,

Thank you for the pach.

This could be expanded a bit. 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. With these small issues addressed,
