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")

I don't believe this is a real bug. The lockdown_reasons array is a
non-empty constant, so temp is guaranteed to be written to by sprintf
before being passed to strlen.
When submitting patches in the future, could you also include an
analysis of the conditions that might lead to the bug, along with the
coverity scan report?
