Hi James & Daniel,

Sorry I didn't make it clear in commit log, but it do based on linux-next.

I think the reason why James think it's not for drm-misc-next
is conflicts exists when this patch being applied. There's conflicts 
because commit <4d4901c6d7> which switched over direct seq_read method 
calls to seq_read_iter should applied before this clean-up patch(linkage 
listed as below).

https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next/+/4d4901c6d748efab8aab6e7d2405dadaed0bea50

I can send a new patch based on mainline if needed.

Thanks.

Qinglang
