From 52338088ef0569290b7eae0759c58a3de494e6c0 Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Sat, 22 Sep 2018 21:09:56 +0530 Subject: [PATCH] arm64/numa: Unify common error path in numa_init() At present numa_free_distance() is being called before numa_distance is even initialized with numa_alloc_distance() which is really pointless. Instead lets call numa_free_distance() on the common error path inside numa_init() after numa_alloc_distance() has been successful.
