[PATCH v3 01/29] bulk: Access existing variables initialized to &S->F when available |
|
Date: |
Mon, 29 Jan 2024 17:44:43 +0100 |
When a variable is initialized to &struct->field, use it
in place. Rationale: while this makes the code more concise,
this also helps static analyzers.
Mechanical change using the following Coccinelle spatch script:
@@
type S, F;
identifier s, m, v;
@@
S *s;
...
F *v = &s->m;
<+...
- &s->m
+ v
...+>
