From 774a075ab5140bb4504e6026bf327021926c3e65 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 3 Jul 2019 14:35:12 +0200 Subject: ALSA: hda: Simplify snd_hdac_refresh_widgets() Along with the recent fix for the races of snd_hdac_refresh_widgets() it turned out that the instantiation of widgets sysfs at snd_hdac_sysfs_reinit() could cause a race. The race itself was already covered later by extending the mutex protection range, the commit 98482377dc72 ("ALSA: hda: Fix widget_mutex incomplete protection"), but this also indicated that the call of *_reinit() is basically superfluous, as the widgets shall be created sooner or later from snd_hdac_device_register(). This patch removes the redundant call of snd_hdac_sysfs_reinit() at first. By this removal, the sysfs argument itself in snd_hdac_refresh_widgets() becomes superfluous, too, because the only case sysfs=false is always with codec->widgets=NULL. So, we drop this redundant argument as well.
