From cf21eb6a9fc2c0d7e529f4c0dfb59fa895bab44a Mon Sep 17 00:00:00 2001 From: Samasth Norway Ananda <samasth.norway.ananda@oracle.com> Date: Tue, 13 Feb 2024 16:19:56 -0800 Subject: [PATCH] tools/power x86_energy_perf_policy: Fix file leak in get_pkg_num() [ Upstream commit f85450f134f0b4ca7e042dc3dc89155656a2299d ] In function get_pkg_num() if fopen_or_die() succeeds it returns a file pointer to be used. But fclose() is never called before returning from the function. Signed-off-by: Samasth Norway Ananda <samasth.norway.ananda@oracle.com> Signed-off-by: Rafael J.
