From c17b658e7978c4c6dbdc238d8b5d94ac2bdd4746 Mon Sep 17 00:00:00 2001 From: Mathieu Poirier <mathieu.poirier@linaro.org> Date: Mon, 12 Feb 2018 13:32:37 -0700 Subject: [PATCH 125/132] perf auxtrace arm: Fixing uninitialised variable Git-commit: d2785de15f1bd42d613d56bbac5a007e7293b874 Patch-mainline: v4.17-rc1 References: fate#325865,fate#325861 When working natively on arm64 the compiler gets pesky and complains that variable 'i' is uninitialised, something that breaks the compilation. Here no further checks are needed since variable 'found_spe' can only be true if variable 'i' has been initialised as part of the for loop.
