Subject: [PATCH 143/217] libcxl: Remove extraneous NULL checks when validating
|
|
|
e0018b |
cmd status
|
|
|
e0018b |
|
|
|
e0018b |
When a cxl_cmd_new_*() function is executed the returned command
|
|
|
e0018b |
pointer is always checked for NULL. Remove extraneous NULL checks
|
|
|
e0018b |
later in the command validation path.
|
|
|

|
|

Coverity pointed these out as 'check_after_deref' issues.
