This file seems to be the "does the submitter look at the patch they are
sending" litmus test.

Does that really do what you think it does?

thanks,

Re: [PATCH] Staging: mt7621-dma: mtk-hsdma.c: Fix Missing a blank line after declarations

[John Oldman]

(this time sent as plain text)

I was not so happy about this one, even though I went and committed it.

Without the blank line checkpatch reports:

WARNING: Missing a blank line after declarations
#160: FILE: drivers/staging/mt7621-dma/mtk-hsdma.c:160:
+ struct tasklet_struct task;
+ volatile unsigned long chan_issued;

So I dumly inserted a blank line to silence checkpatch.

In hindsight maybe a false positive, blank lines in a struct!

Someone may have been there before as there is a previous blank line
in the struct mtk_hsdam_engine :o)

Cheers
John

As checkpatch is just a simple script, it is not always right, don't
blindly follow it.

It can be, but not here.
