Takashi Iwai 774a075ab5 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 98482377dc ("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.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
