The recent commit 87d0e2f41b8c ("usb: typec: ucsi: add a common
function ucsi_unregister_connectors()") introduced a regression that
caused NULL dereference at reading the power supply sysfs. It's a
stale sysfs entry that should have been removed but remains with NULL
ops. The commit changed the error handling to skip the entries after
a NULL con->wq, and this leaves the power device unreleased.
For addressing the regression, the straight revert is applied here.
Further code improvements can be done from the scratch again.

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.
