Don't run lindent. I think checkpatch.pl has a --fix option that might
be better, but once the code is merged then our standard become much
higher for follow up patches.

The original is fine. I don't encourage people to do fancy indenting
with their local variable declarations inside functions but for a struct
the declarations aren't going to change a lot so people can get fancy
if they want.

The problem with a local is if you need to add a new variable then you
have to re-indent a bunch of unrelated lines or have one out of
alignment line. Most people know this intuitively so they don't get
fancy.

Yeah. Lindent is correct here.

The original was better.

No need for a blank. These are closely related.

The new indenting is very wrong.
