Hi Minghsiu,
v6 looks good, but I get these warnings when compiling it for i686:
linux-git-i686: WARNINGS

This is not blocking, but if you can post a follow-up patch for this, then that
would be helpful.

I also got the report from kbuild robot. There are build errors in mtk_mdp_pm_suspend(). Besides, in arch x86, I also have build warning messages in kzalloc() and kfree() used in mtk_mdp_m2m.c. It can be fixed by including linux/slab.h I will upload the patches today.
