DbC is currently only enabled back if it's in configured state during
suspend.
If system is suspended after DbC is enabled, but before the device is
properly enumerated by the host, then DbC would not be enabled back in
resume.
Always enable DbC back in resume if it's suspended in enabled,
connected, or configured state

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.
