Subject: [PATCH] loader/bsd: Check for NULL arg up-front
|
||
|
|
|
||
|
|
The code in the next block suggests that it is possible for .set to be
|
||
|
|
true but .arg may still be NULL.
|
||
|
|
|
||
|
|
This code assumes that it is never NULL, yet later is testing if it is
|
||
|
|
NULL - that is inconsistent.
|
||
|
|
|
||
|
|
So we should check first if .arg is not NULL, and remove this check that
|
||
|
|
is being flagged by Coverity since it is no longer required.
|
||
|
|
|
||
|
|
Fixes: CID 292471
