Subject: [PATCH] vdpa: Fix file descriptor leak on get features error
|
|
MIME-Version: 1.0

File descriptor vdpa_device_fd is not free in the case of returning
|
|
error from vhost_vdpa_get_features. Fixing it by making all errors go to
|
|
the same error path.
|
|
|
|
Resolves: Coverity CID 1490785
|
|
Fixes: 8170ab3f43 ("vdpa: Extract get features part from vhost_vdpa_get_max_queue_pairs")
