Takashi Iwai efb75df105 ALSA: usb-audio: Skip generic sync EP parse for secondary EP
When ep_idx is already non-zero, it means usually a capture stream
that is set up explicity by a fixed-format quirk, and applying the
check for generic (non-implicit-fb) sync EPs might hit incorrectly,
resulting in a bogus sync endpoint for the capture stream.

This patch adds a check for the ep_idx and skip if it's a secondary
endpoint.  It's a part of the fixes for regressions on Saffire 6.

Fixes: 7b0efea4ba ("ALSA: usb-audio: Add missing ep_idx in fixed EP quirks")

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.
