From 140960564d6376fe6b702574a64434a7bc8f085c Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Fri, 19 Mar 2021 09:41:03 +0000 Subject: [PATCH] octeontx2-pf: Fix missing spin_lock_init() in otx2_tc_add_flow() The driver allocates the spinlock but not initialize it. Use spin_lock_init() on it to initialize it correctly.
