Takashi Iwai bfc4ccc0bc ALSA: usb-audio: Fix init call orders for UAC1 
commit 5fadc941d0 upstream.

There have been reports of USB-audio driver spewing errors at the
probe time on a few devices like Jabra and Logitech.  The suggested
fix there couldn't be applied as is, unfortunately, because it'll
likely break other devices.

But, the patch suggested an interesting point: looking at the current
init code in stream.c, one may notice that it does initialize
differently from the device setup in endpoint.c.  Namely, for UAC1, we
should call snd_usb_init_pitch() and snd_usb_init_sample_rate() after
setting the interface, while the init sequence at parsing calls them
before setting the interface blindly.

This patch changes the init sequence at parsing for UAC1 (and other
devices that need a similar behavior) to be aligned with the rest of
the code, setting the interface at first.  And, this fixes the
long-standing problems on a few UAC1 devices like Jabra / Logitech,
as reported, too.

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.
