commit e17b02d497 upstream.
When extcon is used in combination with dwc3, it is assumed that the dwc3
registers are untouched and as such are only configured if VBUS is valid
or ID is tied to ground.
In case VBUS is not valid or ID is floating, the registers are not
configured as such during driver initialization, causing a wrong
default state during boot.
If the registers are not in a default state, because they are for
instance touched by a boot loader, this can cause for a kernel error.

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.
