[PATCH v1 06/18] perf buildid-cache: Fix use of uninitialized value

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The buildid filename is first determined and then from this the
buildid read. If getting the filename fails then the buildid will be
used for a later memcmp uninitialized. Detected by clang-tidy.
