[PATCH v3 35/44] error: Eliminate error_propagate() manually |
|
Date: |
Mon, 6 Jul 2020 10:09:41 +0200 |
When all we do with an Error we receive into a local variable is
propagating to somewhere else, we can just as well receive it there
right away. The previous two commits did that for sufficiently simple
cases with Coccinelle. Do it for several more manually.
