Subject: [PATCH] sys-utils: fix add NULL check for mnt_fs_get_target return
|
|
value
|
|
|
|
The static analyzer flagged a potential issue: the return value of
|
|
mnt_fs_get_target(fs) could be NULL, but it was dereferenced without
|
|
a check. This could lead to undefined behavior.
|
|
|
|
Added a NULL check before using the tgt pointer. If tgt is NULL,
|
|
the current iteration is skipped.
|
|
|
|
ChanChanges:
|
|
- Added if (!tgt) check before using tgt.
