Xu Yang 2588c29afd usb: core: hcd: only check primary hcd skip_phy_initialization 
commit d2ec94fbc4 upstream.

Before commit 53a2d95df8 ("usb: core: add phy notify connect and
disconnect"), phy initialization will be skipped even when shared hcd
doesn't set skip_phy_initialization flag. However, the situation is
changed after the commit. The hcd.c will initialize phy when add shared
hcd. This behavior is unexpected for some platforms which will handle phy
initialization by themselves. To avoid the issue, this will only check
skip_phy_initialization flag of primary hcd since shared hcd normally
follow primary hcd setting.

Fixes: 53a2d95df8 ("usb: core: add phy notify connect and disconnect")

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 reStructuredText 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.
