[PATCH 23/46] qapi: Smooth error checking with Coccinelle |
|
Date: |
Wed, 24 Jun 2020 18:43:21 +0200 |
The previous commit enables conversion of
visit_foo(..., &err);
if (err) {
...
}
to
if (!visit_foo(..., errp)) {
...
}
for visitor functions that now return true / false on success / error.

Eliminate error_propagate() that are now unnecessary. Delete @err
that are now unused. Tidy up line breaks and whitespace.
