From 3bc3d30ca324bfc3045a1a7fe1f5fe5ad5d92fd9 Mon Sep 17 00:00:00 2001 From: Prarit Bhargava Date: Thu, 5 Sep 2019 08:03:11 -0400 Subject: [PATCH] tools/power/x86/intel-speed-select: Fix memory leak cpumasks are allocated by calling the alloc_cpu_mask() function and are never free'd. They should be free'd after the commands have run. Fix the memory leaks by calling free_cpu_set().
