Subject: [PATCH 22/51] common: remove unnecessary free
|
|
|
|
This commit drops an erroneous free call, that would
|
|
potentially free a dangling pointer.
|
|
|
|
Luckily the error condition can never occur because the
|
|
error code checked is never returned, so the free call
|
|
is dead code.
|
|
|
|
This commit removes the free call. A subsequent commit
|
|
will fix the error code checking.
