Before this patch usb_phy_roothub_init served two purposes (from a caller's point of view - like hcd.c): - parsing the PHYs and allocating the list entries - calling phy_init on each list entry While this worked so far it has one disadvantage: if we need to call phy_init for each PHY instance then the existing code cannot be re-used. Solve this by splitting off usb_phy_roothub_alloc which only parses the PHYs and allocates the list entries. usb_phy_roothub_init then gets a struct usb_phy_roothub and only calls phy_init on each PHY instance (along with the corresponding cleanup if that failed somewhere). This is a preparation step for adding proper suspend support for some hardware that requires phy_exit to be called during suspend and phy_init to be called during resume.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
