From f9993480214f1345497875ed363a52b7ef7e33db Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Sat, 11 Jan 2020 14:33:25 -0600 Subject: [PATCH] ALSA: timer: fix nsec/sec initialization confusion MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit GCC reports a warning with W=1: sound/core/timer.c: In function ‘snd_timer_user_read’: sound/core/timer.c:2219:19: warning: initialized field overwritten [-Woverride-init] 2219 | .tstamp_sec = tread->tstamp_nsec, | ^~~~~ sound/core/timer.c:2219:19: note: (near initialization for ‘(anonymous).tstamp_sec’) Assigning nsec values to sec fields is problematic in general, even more so when the initial goal was to survive the 2030 timer armageddon.
