Hi,
getting rid of lines with multiple instructions, separated by comma is
certainly a good idea.
One nit pick, though:

I can remember patches being rejected with one line statements in a condition,
surounded by braces.
I just read up Documentation/process/coding-style.rst, to be sure this still is up-to-date.
It's not a must, but line 180 says:
"Do not unnecessarily use braces where a single statement will do."
So if this is about coding style cleanup, IMO you should remove braces from single line
statements.
I haven't reviewed every line, but I expect you only split up comma separated instructions
into separate lines and added braces?
Afaik there isn't a specific tag, but having:
cleanup only: No functional change
in the changelog would be nice for people looking for fixes to backport.
Otherwise, I think this is a worthful cleanup.
Thomas
