commite835c0a4e2upstream. Commitc4a5153e87("usb: dwc3: core: Power-off core/PHYs on system_suspend in host mode") replaces check for HOST only dr_mode with current_dr_role. But during booting, the current_dr_role isn't initialized, thus the device side reset is always issued even if dwc3 was configured as host-only. What's more, on some platforms with host only dwc3, aways issuing device side reset by accessing device register block can cause kernel panic.

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.
