Fix regression in how intel_haswell_fixup_connect_list()
results are used in hda_read_pin_conn(). Use of
snd_hda_get_raw_connections() in hda_read_pin_conn() bypasses
the cache and thus also bypasses the overridden pin connection
list. On platforms that require the connection list fixup,
mux list will be empty and HDMI playback will fail to -EBUSY
at open.
Fix the regression in hda_read_pinn_conn(). Simplify code
as suggested by Takashi Iwai to remove old
intel_haswell_fixup_connect_list() and copy the cvt_nid list
directly and not use snd_hda_override_conn_list() at all.

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.
