From: Tanya Agarwal <redacted>
The static code analysis tool "Coverity Scan" pointed the following
details out for further development considerations:
CID 1486102: Uninitialized scalar variable (UNINIT)
uninit_use_in_call: Using uninitialized value *temp when calling
strlen.
Conclusion:
Initialize array before use in lockdown_read() to satisfy the static
analyzer.
Fixes: 000d388ed3bb ("security: Add a static lockdown policy LSM")
Signed-off-by: Tanya Agarwal <redacted>

V2: add Fixes tag and reword commit description
V3: use "" initialization instead of {}
