[ Upstream commit 5e5fd36c58d6c820f7292ee492c3731c9a104a41 ]
Currently if a fscanf fails then an early return leaks an open file pointer. Fix this by fclosing the file before the return. Detected using static analysis with cppcheck:
tools/power/x86/turbostat/turbostat.c:2039:3: error: Resource leak: fp [resourceLeak]
