From f4b7699c88f74aeb9983aa7ef438f8e7e72eb8c5 Mon Sep 17 00:00:00 2001 From: Olivier Matz Date: Mon, 11 Sep 2017 17:13:25 +0200 Subject: [PATCH] net/qede: fix compilation with -Og MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The compilation with gcc-6.3.0 and EXTRA_CFLAGS=-Og gives the following error: CC qede_rxtx.o qede_rxtx.c: In function ‘qede_start_queues’: qede_rxtx.c:797:9: error: ‘rc’ may be used uninitialized in this function [-Werror=maybe-uninitialized] return rc; ^~ If there is no Rx or Tx queue, rc will not be initialized. Fix it by initializing rc to -1.
