This is already resolved by commit 76cd0c7cc20f ("Staging: comedi: Added 
blank lines to fix coding style issue") in the 5.10 kernel (from the 
year 2020):

As Ian pointed out, this was fixed a very long time ago.  Please always
work against the latest kernel tree so you don't duplicate work that was
already done.

I suggest going through the tutorial on kernelnewbies.org as well, this,
and the previous submission, had a number of problems (hint, this patch
was corrupted and couldn't be applied.)

good luck!

Please don't use html email (the mailing lists reject it) and don't
top-post (makes having technical discussions impossible.)

You are looking at the wrong branch, ignore the `master` branch in
there, use staging-next please.
